What does the word 'dicta' ('dita'?) mean in the song 'Who's That Chick?'?

The song 'Who's That Chick?' by David Guetta featuring Rihanna features the following line in the chorus:

She's been a crazy dicta, disco fever and you wonder...

Lyrics websites disagree on the word in bold: 'dita' seems to be a common alternative. To my ear it sounds more like /ˈdɪktə/ than /ˈdɪtə/ or /ˈdɪttə/. (You can listen here - the chorus starts at about 1:10.)

I can't find any definitions of 'dita' (or 'ditta' or 'ditter' etc.) that make any sense in the context of this song.

As for 'dicta', there is a sole entry on UrbanDictionary:

A woman that appears to be quiet when you first meet her, but once you begin unraveling her personality you realize that she scarily independent.

While this might fit the song, I can't find any evidence for it apart from an anonymous answer on Yahoo! Answers. The wording of the answer is very similar to that of the UrbanDictionary definition; both may well have been written by the same person. The definition happened to appear in December last year, not long after the song was released.

Perhaps the lyricist was out of ideas and decided to invent a new word.

"Dita" is a name. Madonna takes it in the song Erotica and in her book "Sex". Dita was a Polish actress. Dita Von Teese, also inspired by the actress, took her name.

David Guetta's own youtube channel spells it DITA http://www.youtube.com/watch?v=BOdmf4N5aPE&t=1m42s

Dita von Teese comes to mind - she is a crazy diva :)

Not an answer to that question specifically, although I was looking for the answer which lead me here and I like what I found. Various websites have all the lyrics but in my opinion not one has them all correct. Between them I think you can find the correct lyrics. There's "she's a mean and crazy Dicta" "she's been a crazy dita" "Disco Diva" "Disco Fever" (obviously diva is correct here). The one that seems to be the most wrongly heard though is when it goes "ultrasexual the night has got me love sprung" Loads of websites/YouTube clips have the words: "I will try to set/sex you up" instead. Listen to it, she clearly says "ultrasexual."
