skull pop 

Can be administered with either hand but the act of slapping someone in the back of the head. Depending on the speed of the hand it can also be called a "0-90" (meaning the hand accelerates to 90 mph before striking the back of the head). A perfectly administered "skull pop" will most of the times cause the head to jerk forward.

I was just sitting here minding my own bitnis and Medo came up from behind and skull popped me.

You better get your ass home. Dads pissed and I think he'll be dishing out skull pops like candy.
