A moment of extreme joy after driving your Z06. Usually acompanied by a discharge of drool over the left part of your lower lip.
I had a Zgasm while driving my Z06 after my MY/ Blk this afternoon. I've got the new LPE Magnuson Supercharger.

A z-gasm is where you blow your load at a zoo. Near the panda exhibit. Often due to the feminine wiles of the various wild creatures.
I swung by the pandas, and that was cool, but those monkies got me rolling, I almost kicked out a z-gasm.
