1. "I'm very familiar with my own nut 'cause I'm constantly spattin' it off in groupie's faces. Sshplaaaat! Right in their face! Get it all! Get painted, freak! I say get painted when I'm painting them with my jiz." -Violent Jay

Unlike the other people seem to suggest for this entry, a funboy is not necessarily gay. He is more of a metrosexual; the kind of really stylish guys that dress in expensive clothes like they might be gay, but are just really stylish.
I saw a couple funboys headed to the club wearing their cashmere and pink polo shirts.
