Plan B

A sexually oriented prank where you have sex on someone's pillow, and ejaculate on the other side. So, when the victim lays on their pillow, and it smells a bit like sex, they instictively turn it over, and lay their head on the other side, or Plan B.

Dave, my roommate, ate all the food in the apartment, so I gave him the old "Plan B".
