The same as a normal pimp-slap, where you assault your target by slapping him/her with the back of your hand, except you run your hand down your own butt crack 1st. This marginalizes and denigrates the offender even further.
I was so upset with this loudmouth drunk at a bar, that I had to shut him up; so I dirty pimp-slapped him into submission.
