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.

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"
