Dropping a crap in the toilet tank (instead of the bowl).
JJ got so drunk he laid a top shelfer at Angelina's party.

Great payback to someone who's done ya wrong....Go to their house...excuse yourself to go to their bathroom. Lock door. Remove top of toilet...drop a duece...place top back on...Hence the term Topshelfer....
This dude owed me money so I gave him a topshelfer the other night at his house....
