Term coined by Denzel Washington in "Training Day"
Meaning:
one who is, while at the same time actin disloyal, is also actin bitchmade and like a punk, and is a fool-ass for thinking he gonna get away with it.
Guy 1: Yo, man last night one thing lead to another and i fucked yo girl. But it bros before hoes right?
Guy 2: YOU DISLOYAL-FOOL-ASS-BITCHMADE-PUNK!!! I was gonna propose to her tonight. Now i gotta kill you AND her!!
More often than not, it is used in a derogatory manner. Can also be a term of endearment. Personally I mostly say it when someone tells me they did something I have no interest in.
That one asshole who dresses like he shops solely at Mens Warehouse. You will often find a fruity fool coming to the aid of a female after falling, also referred to as "white knighting"
The fool portion can be put how you want it. For example if you see a wanna be mexican cracker you can say 'Salsa ass fool'

Fruity ass fool: Hey back off bro, she's having drinks with her friends not you!
Your Friend: This fruity Ass fool Friend 2: Yeah Back off fruitcake
