Typically used as an adverbial or adjectival acronym meaning, "as fuck", AF refers to a higher, more significant version of the verb. When you are "extra" tired, you are tired AF. Might also work with nouns, although grammatically might be disjointed.

Jesus, did you misspell ‘as if’? As af is stupid because it’s essentially ‘as as fuck’ and that is not grammatically correct.
1. Girl1: I was typing to one of my friends and accidentally typed ‘as af’ like a moron.
2. Girl2: that’s funny as af!
Girl3: get out. Get out of my apartment. Get out now.
2. Girl2: that’s funny as af!
