Alright!!!! This act is only done by the playas out there knowing that they can get some!!! It is when u are dancin ur ass off...literally!!!!! The guy is setting his behind on a resting area while the girl is in front freakin the hell out of the boy. While the guy is getting his groove on with a sway of the hips, knowing that his ass is being rubbed against what he is leaning on, he gets a massive scab just above his ass crack!!!!!
