Double Decking

Taking a dump into the toilet tank so when a person flushes the toilet they are astonished to see a turd come down.
Marlene was shocked at the Omega Mu House party when she flushed the toilet and a big nasty frat boy turd came down and she realized that she had been the victim of double decking.

(WARNING: Do not try this. You could easy break a toilet. )
