Top tiering 

Top tiering is the art of pooping into the top part of a toilet where the water on deck to enter the bowl waits. The next (few) people to flush the toilet will unknowingly flush bits of your turd into the bowl.

"This party sucks, lets top tier and get the hell out."
"Good plan, top tiering rules."
