Slatering the upper deck

This technique is for the most skilled of slaterer's. One must be nimble and quick in order to accomplish this feat. It involves combining the classics "slatering" and the "upper decker." You sit on the top of the toilet in the AC slater position (from saved by the bell) and take a hot steamy dump in the upper deck.

Jorge: Hey man, what's wrong. Why is your face all bruised on your left side?

Carlos: Shit man, I was slatering the upper deck on your can and I fell off.

Jorge: What the hell does that mean man. What's that brown shit on your shirt and pants.

Carlos: Shit.

Jorge: You are f'd man. Why do I hang out with you.
