Someone who is fake as fuck. More specifically this person is also flailing as fuck, and flaky as fuck.. making them a triple FAF. This fake, flailing and flaky as fuck person is notorious for getting drunk and throwing their body and limbs all over the place, including flailing their pu$$y open for men. This FAF is flaky and fake.. notorious for ditching plans with friends the minute one of her men texts her!

An acronym of "Fake as fuck", a term popularised by rapper Del Tha Funkee Homosapien in his 'Both sides of the brain' album (2000), denoting his view of two-faced people who say one thing to your face, and another behind your back.

"If you're brown nosin' in the industy (you fake as fuck)
Wanna pretend that you're a friend to me (you fake as fuck)
Funny style record companies (you fake as fuck)
Weak ass MC wannabe's (you fake as fuck)"
