Upper Decker

When someone poops in the top part of a toilet, (the part that you have to take the top off) so when someone else goes to the bathroom and flushes the toilet instead of clean water coming in and filling the toilet, shit water comes in. This is done as a pratical joke, usually done at parties.

Guy 1:Hey I just did that Upper Decker in the toilet upstairs and Jennifer went in there.
Guy 2:Hahahah, what'd she do when she came out?
Guy 1:I don't know, she's still in there!

Spartan Upper Decker

When one is frustrated and angered to the point of giving the accused a most-deserved upper decker and feels the need to voice their anger- they must, just before dropping a lung in the toilet tank, shout loudly- "This is Sparta!!!" as spoken in the movie 300. After this is spoken, one would shit with vengeance into the tank.

Angry person- That bitch of a waitress ignored our table for over half-an-hour because they add automatic gratuity to the check, so I will leave them my opinion of their service in their toilet tank in the form of a Spartan Upper Decker.

Friend 5 minutes later- Did you do it?

Angry person- I showed no mercy!
