There’s a pronunciation guide in the original documentation, and that didn’t end the debate.

Humans are even more horrible that this first glance suggests. Imagine, one day, the debate truly ends and a single pronunciation for GIF is universally established and recognized by everyone. A group of humans will start to intentionally mispronounce it (or misspell it) just for the aggravation it will generate in others or for their own amusement.

This is where the meme-like behavior of deliberately misspelling the popular phrase (at the time) “all correct” as “oll korrect”. This was later abbreviated as “o.k.” and then eventually “ok”. A phrase we likely use dozens or hundreds of times a day is meme-speak from 1839. source
