Phat is an adjective to describe approval in Hip Hop culture. Hence, someone or something that is phat could be cool, rich, entertaining, intelligent, fly or otherwise to be admired. The term derives from Black English Vernacular(Ebonics)
as a deliberate misspelling of the word fat. Fake etymologies for "phat" state that the word originated as an acronym for "Pretty Hot And Tempting", "Plenty of Hips And Thighs" or "Pussy, Hips And Tits".
