When You run up to your friend (must be a male) and hit him in the balls. You must also yell sllab, that is the most important thing. Kicking is not counted as a sllab, so don't try it. The word comes from balls backward. This is something you do for a good laugh only, and not for any other reason.
John ran up to Tim and hit him in the balls and yelled Sllab.

the word "Balls" (implying testicles) Spelled Backwards. It seems to have varied usage.

In the way I learned it, Often followed by an argument between the two parties at hand. (See example)
Person A: Hey Guess what?

Person B: What?

Person A: Sllab! (NOTE: PERSON B MUST SAY "WHAT" IN ORDER FOR PERSON A TO RELPY "SLLAB")
This argument often follows for those "in the know":

Person B: Dickbag/Stickbag (depending on whether person B is in JHS Percussion or not)

Person A: Down your throat

Person B: Hope You choke

A variant has Person A replying to "what" with "Sllab Dickbag," creating a role reversal and ends wit person A winning the "Argument"
The same thing as balls but reverse. Mainly used by internet folk.
"haha, man I'm just busting your sllab
