The act of slapping, moving your entire arm in a " slow motion" to seem as if you are in slow motion, when your palm is 5cm away from the subjects face, the speed increases so you slap them hard.
this creates the effect used in the movie 300.
it also looks funny

A variation of the bitch slap, when someone is acting up, you slap them with each of your hands and feet, also known as the hard 21 in the case of the man with 6 fingers on his right hand from The Princess Bride.

When you lie, and make your love partener agree to take a shit. Little does he/she know while they are taking the shit which is on a toilet, you push down on them hard so they get wedged in the toilet seat. You proceed to slap them wiv your penis, or dildo, until both cheeks are sevearly bruised.

When one has peanutbutter on their hand and yells "peanutbutter slap" and slaps them hard on the face

Bitch Slap also known as Pimp Slap, is when you take your hand and slap that Bitch back and forth until the hit the ground. Lets practice, ''take what ever hand is more dominant and raise it up, have the hand level to the persons nose, then slap them as hard as shit on a brick, it helps if you say left slap and right slap, then you last you say nigga please and slap that bitch until they are gone'' If ''Bitch Slapping'' does not cause much harm then SHANK the bitch.

where twat townies come up to a person and slap them whilst one of their mates record it on a cam fone
There is, however, a reversal but u gotta get your timin right (u can see wen its gonna happen cos a chav will be walkin fairly quickly to you and close by someone will have a fone out aimin roughly in ur direction. when he brings his hand up hes vulnerable, and then you slap him, AS HARD AS POSSIBLE!!! then run off give em the finger if you want just to add effect
(3 times out of four ive pulled this one)

Happy Slap - Un like the others above some true some false, happy slapping came about with the making of video cameras, its been about since the HI-8s and now moved on to mobile phones.

A typical stereotype is a person aged 14-18 years, waring a cap, hoodie or a stripy jumper with also market bought jogging bottoms with the known 3 stripes going down towards the feet also waring trainers like Reebok or Nike sometimes but rarely a skateboarder make like DC.

You'll know when they'll attack you as it happens as soon as they or you sit down and the mobile will be off to the seat on your left/right side or even right behind you if it happens in the street.

One way to combat this is to carry your own camera/mobile camera and just as or after they hit you get a picture of them give it to the police or what not stating you want to press charges as they attacked you.

You could do as shown above, catch them by suprise and hit them in-stead but if so make sure you hit them hard enough so that you can run.
