a beiber
A beiber is when two guys are doing a double blowjob and one of them is fingering the other’s butt like it’s a job.
My uncle and his friend did a beiber at the party and it was so loud, the neighbors called the cops.
My brother and his friend did a beiber in the garage and it smelled like old pizza.
At the gym, I saw two guys doing a beiber and it looked like they were trying to kill each other.
