A black bison is a sexual act in which a male has anal sex with a female, while the female simultaneously shits on his dick. Then as the male prepares to ejaculate the woman deepthroats his penis, swallowing both the male's semen and her own feces.
My wife finally pulled a black bison with me last night, it was awesome.
The black bison is my favorite sexual act.
a leader, a ruler, a king, a man who can lead the whole team like they’re a brother to him and he don’t care what others think. Huncho bison usually has a beard and a sick ass truck.
