Both words shakin' and happnin', conveniently wrapped into one word. Both words alone have gone out long ago, but slapp'nin brings it all back in style.

"So I said: that's what your dad said." John quipped. The group sighed. Suddenly, Arin's hand moved with incredible quickness and John doubled over holding his crotch.

Ninja bitch-slap 

When a regular bitch-slap just isn't enough, a Ninja bitch-slap incorporates the ancient use of covert agents or mercenarys of feudal Japan specializing in unorthodox arts of war. The functions of the ninja included espionage, sabotage, infiltration, assassination, as well as open combat in certain situations. The underhanded tactics of the ninja were contrasted with the samurai, who were careful not to tarnish their reputable image.

A properly executed Ninja bitch-slap will probably land you a top spot on the bad ass list, right under Chuck Norris.

Scott: I wouldn't mess with Trevor if I were you, man.

Scott: Oh, did he, Joey?

Ninja Slap

A game involving a group of people (usually over three). Everyone must get in a circle and on the count of three, must take a random pose. After that, going clockwise, one person at a time must try to slap another person's hand (any person). If the person hits another person's hand, the person who was hit must leave the circle. Whether successfully hitting or missing, one must stay in that pose. Only the person who's turn it is and the person who he/she has aimed for may move at a time. The person who is aimed for doesn't go next; the next person is always to the left of the person who just went. The game ends once only one person is left. This game is usually played to pass the time.

Today, in line for the concert, we played ninja slap while the others in line watched in disbelief with a confused look on their faces.
