it's where you take your fingers and you snap three times as u make a z in the air... it means " i know u just didn't" or "bring it on" or "your bitch ass just got served". It is usually used by ghetto masters or white wangstas.
Right after Talisha stole my boy, I gave her the z snap to let her know just how i felt. Bring it on, beeyotch!

When a person (usually a girl) snaps three times in the air in the shape of a Z. People do it to mean 'oh no she DIDNT!' or 'u got told!' It's gotta be done with a lot of attitude.
after a gay guy hits his cheating boyfriend with a purse and wants to finish off, he could do the z-snap with a little "mmm-hmm" before walking off leaving his EX boyfriend humiliated
