B.M. from the front

1.)A big, black, dick. When a black man is so hung that it looks like he is taking a shit from the front instead of his ass. Therefore he is making a Bowel Movement from the front. 2.) Horse weiner on a black man. 3) Donkey weiner.

When Sally, a white girl, first saw Dameetrion's penis, she got scared because she thought Dameetrion was taking a B.M. from the front.
