look up any word, like lemonparty:
 
1.
Fyat is another way of spelling PHAT, Pretty Hot and Tempting.

Pronouced - Fee - Yat.
Although when this word was orignated, in the mid to late 90's it never caught on. Mostly due to the fact that F.Y.A.T. was not an acronmyn for anything.
In fact in may have only been used once in its entirity
"Dude, that chick FYAT."

"Only FYAT girls ride with me, and I am not talking about F.A.T."
