Name and origin of writing with period after each word

It may be limited to the web ecosystem, but I've read a lot of those sentences lately, where each word is followed by a period.

Examples:

Oh. My. God.

Best. Job. Ever.

No. F***ing. Way.

Putting each word on its own hints the readers should give their full attention to each and every one of them.

Does this technique have a name? Can its origin be traced back to a book or article?

Technically, the simplest answer would be "punctuated speech."

punctuated — emphasize something: to do or say something in order to add emphasis

But this specific pattern is extremely common in music and goes by the term "staccato". The Wikipedia entry has some good examples of music played with and without staccato and it perfectly matches the vocalized pattern used when reading this type of passage out loud.

The dictionary definition includes this:

staccato — composed of or characterized by abruptly disconnected elements; disjointed: rapid-fire, staccato speech.

The key part of staccato is not the speed at which is played but the disjointed, punctuated feeling of each note or word.

Comic Book Guy from the Simpsons. That's your answer.

For more on the Simpsons answer (unfortunately I do not have enough reputation to add to the comments), there was a forum for dedicated Simpsons fans called alt.tv.simpsons which may be the source of the multiple periods. One of the fans commented that one of the episodes was the worst episode ever. The writer David S. Cohen took that comment and used CBG as a response and forming his most quoted catchphrase "Worst. Episode. Ever." I believe the first instance of CBG saying this is in the 1997 episode "The Itchy & Scratchy & Poochie Show." I had already heard this story but had trouble finding a source. Wikipedia references it in https://en.m.wikipedia.org/wiki/Alt.tv.simpsons#Relationship_with_the_writers

In English the period is really meant to indicate a long pause in speaking (like would happen at the end of a sentence). As such, I suspect its history of use to designate long pauses for emphasis in this way goes back pretty much as far as the period itself does.

It's going to be difficult to trace. There must, of course, be a initial appearance of this usage in writing, but that may be ephemeral. Now it's popping up all over the place, especially in advertisements. It seems to me to have originated in common speech, when someone -- with tongue lightly inserted in cheek and mildly humorous intent -- said something with that particular phrasing, in order to emphasize the superlative, thus: "Man, I went to Las Vegas and won a million bucks playing bingo, and that actress Jennifer what's-her-name invited me to her Oscar party in L.A., and I got picked to star in the new James Bond movie, and that was just Saturday! Best. Weekend. Ever."
