What does "ratchet" mean and when was it first used?
Solution 1:
When a slang word catches on, students of language often have a difficult time figuring out its meanings and origin. This, I suspect, is because it emerges not like Athene—a fully formed adult released from the mind of Zeus—but like several thousand frog eggs—similar in appearance to one another but bewildering in number and neither well defined nor mature.
Eventually usage of a slang term X will probably coalesce around one or a few more-or-less clearly understood meanings, but in the meantime the only reasonable way to answer questions such as “what does X mean?” is to identify as many of the ways in which the word is being used as you can.
Without attempting to be exhaustive, I took my frog egg search to the least professional-looking authority I could easily find—which turned out to be Caitlin Corsetti’s “Define That: Ratchet” blog post at Gurl.com—and then consulted not Ms. Corsetti but the commenters responding to her post. From them I learned the following things about ratchet.
What does 'ratchet' mean, and how is it pronounced?
Ratchet [is] used to describe someone means nasty, ghetto or trifling. —Janet
Ratchet also means a situation or process that is perceived to be deteriorating or changing steadily in a series of irreversible steps. It is used as a term for something low class or deteriorated. Similar to how we use the term ghetto. —NyxoftheNight

I have heard my teen-aged granddaughter use this word in reference to her own hair, and she was completely unable to define it or explain what she meant by it. All she could say was, You know, grandma, it’s just rachet! —cat
It’s just simply a mispronunciation of “wretched”. The same people that use it often describe a “ratchet girl” [as] someone that wears torn “stalkings”. —JBW
It is a pure homonym that has nothing to do with a ratchet wrench, or “wretched.” It means RAT SHIT. —Becky
The first time I asked someone for a definition for this slang, I was told it meant “A woman who’s only good for one thing — getting a nut off … like a ratchet.” —Scott Simpson

It is a derivation of the two words “rat” and “shit” as in the situation is, person is, place is so bad it is as bad or worse than “rat shit.” Totally trash talk. —Lily Bear

The term came from Cedar Grove [in] the City of Shreveport Alabama. Popularized by the song, “Do Tha Ratchet” True origin was spun out of slurring the word WRETCHED Now has become a massively overused typo. —Matt
watch emanuel & philip hudsons she ratchet video —selena
Is it a "good"/positive word, or "bad"/negative, and has this changed in any way?
The current slang use of this word has a very nasty, biting undertone to it. The other comments in this thread alone support the connotations of being undesirable. —cat
About 20yrs ago I somehow caught a nickname (ratchet) due to my ability to fix or repair nearly anything. I understood It’s relation to my daily work and eventually I got used to it. I was told by a college girl I should never be ratchet, it completely through me off and I was simply looking at this girl as if she was crazy. —Adam Draughn
The experts above have spoken pretty clearly about what ratchet means, where it came from, and so on. I would only add that Emmanuel N Phillip Hudson uploaded their “Ratchet Girl Anthem” (cited by selena above) to YouTube twice (on January 16, 2012, and April 26, 2012) and that the two versions have accumulated a combined 56.1 million views. With regard to the mystery of the sudden popularity of ratchet, I think we may have a couple of major suspects (if not the actual perpetrators) here.
Lava House and Lil' Boosie's "Do tha Ratchet" (cited by Matt above) deserves some attention because it is considerably older than "Ratchet Girl Anthem." According to LyricWikia, it was released in 2006. The most frequently watched YouTube video for this song was posted on July 26, 2009, and has garnered an impressive 793,000 views despite being a static image accompanied by Lil' Boosie's audio track; still, 793,000 isn't 56.1 million.
As to whether ratchet is meant to be generally understood in a positive or a negative sense, that aspect of the term may well be in flux, just as everything else about it appears to be. In Lil' Boosie's world, ratchet is almost an environmental term: It applies to men (including LB himself) and to women, and it describes most of their doings in the neighborhood where he lives. In contrast, the Hudsons use ratchet specifically in connection with women and do not indicate any sympathy for anyone so described.
Speaking as a complete outsider, with no prior knowledge of ratchet as post–Jimmy Cliff slang, I have to say that the term as used by the Hudsons reminds me quite a bit of skanky, which derived from skank (“An unattractive woman; a malodorous woman; =SKAG,” according to Robert Chapman and Barbara Kipfer, Dictionary of American Slang, third edition [1995]). Here is the Chapman & Kipfer entry for skanky:
skanky or skank-o-rama adj 1980s teenagers fr black Nasty; repellant; =GROTTY, SCUZZY, TRASHY: The girls were somewhat skanky, with lank hair and rotten posture—Richard Price/ ...you moved, the earth moved. Skank-o-rama—Sassy
Both skanky and ratchet (as used in the Hudsons’ comical YouTube video, anyway) are not gender-neutral terms, though none of the Gurl.com experts expressly makes this point about ratchet.
It will be interesting to see whether the gender connection that "Ratchet Girl Anthem" promotes influences the long-term sense of the word, notwithstanding Lil' Boosie's earlier, more broadly applicable sense of the term. The crucial factor here, probably, is the proportion of users who base their knowledge of the term on the Hudsons' song versus the proportion of those who adopted the term as it was used in the older Shreveport, Louisiana, tradition.

I have a 1992 use of "ratchet-ass" in the lyrics I'm So Bad from an album by UGK. I will post only a snippet of it here:
... get your ratchet ass out my fuckin do'
Cause I'm Pimp C, I put a bitch in her place
Reader discretion is advised.
P.S. I wonder if it's a variant of raggedyass ?
NORA: I better wait outside for Joan, 'fore you make me go in the kitchen and get me something an' there be blood all ova' these raggedyass flo's!

From the article "Who You Callin Ratchet?" found on The Root:
What arguably started as a Southern rap dance at the turn of the century and then expanded to describe a relatively positive expression of energy has now become a worthy rival to the word "ghetto." It is most typically used to describe outrageously uncivilized behaviors and music -- often with women as the butt of the joke.
[...] "Then, over the years, the term evolved into something to describe a type of behavior or way of life."
The origin of the dance and term is largely given to Shreveport, La. (aka "Ratchet City"), where the word has been in circulation since the late 1990s.
"Ratchet" is a word that was intended to describe someone who is "all the way turnt up," "buck," "crunk," "hyphy" -- take your pick. It's now plumbing the depths of "Hood Gone Wild" waters but may prove to be buoyant enough to swing back in a positive direction with the passage of time.
