A gay man--one who is usually somewhat accepted or useful to straight and/or macho type guys…a dude that smokes or “puffs” on dick.
“Dude, I was gettin all pissed off cuz that guy was dancin with my girl and shit. But then I realized he was just some fuckin puffa.”
“You know that kid is alright even if he is a puffah.”
“At first I was annoyed to see a puffa at my favorite local bar, but it’s actually kinda convenient—he dances with my chick and keeps her amused. I can hang out with my buddies, shoot some pool and shit and I don’t have to worry about her because that fuckin puffah ain’t interested in her.”
