As Fuck Af
"As Fuck," commonly shortened to "AF," is an English slang intensifier that follows an adjective to amplify it, as in "tired AF" or "cold AF." The full phrase traces back to late-1980s West Coast rap, and the abbreviated "AF" took off on Twitter in the 2010s as a character-saving shorthand.
Overview
"As Fuck," abbreviated "AF" and occasionally spelled "asf," is a slang construction that gets tacked onto an adjective to crank up its intensity. Instead of saying something is "very hot" or "extremely tired," a speaker says it is "hot AF" or "tired AF"1. The phrase works with almost any descriptor, which is a big part of why it stuck.
The two-letter version reads as almost punctuation online, especially on platforms with tight character limits5. It sits at the end of the sentence, doing the same job an intensifier like "as hell" or "really" would, but with more edge and less to type. That combination of function and brevity is what pushed "AF" from spoken slang into everyday text-message and Twitter vocabulary6.
How It Spread
How to Use This Meme
The typical convention is to place "AF" or "as fuck" directly after an adjective for emphasis, as in "bored AF," "cute AF" or "broke as fuck." It often replaces intensifiers like "very," "super" or "as hell," and is common in casual texts, tweets and captions rather than formal writing5. Some users write it lowercase ("af") or as "asf," depending on the platform and tone1.
