According to the Rap Dictionary, "[t]he term 'Fuck Boy' originates from Atlanta, GA. It is used to mean a weak man who can't get right." The Online Slang Dictionary defines a fuck boy as "a male who tries to be something that he knows nothing about."

And rapper/singer Lyssi is frankly sick of 'em. So, in a club-minded, foul-mouthed addition to the lineage stretching from TLC's eternal "No Scrubs" to "Bills Bills Bills" by Destiny's Child, her and her Bay Area godfather E-40 proceed to eviscerate these deadbeats in a variety of suitably devastating ways. In short: get your game up, bro's.

E-40 will be be at Showbox Sodo on Monday night in support of G-Eazy.
