A gay male usualy sounds like justin bieber who takes large amounts of cock in his ass,Thus making him a humbum, They usualy scream OHHHH FREEDDD and ride pink bikes on christmas wearing tutus and getting fucked in the ass in a semi truck,
Gay fag: Hey sexy why dont you call me humbum in that semi
Guy: Oh hell nah bitch i dont roll that way
Guy: Oh hell nah bitch i dont roll that way
