Deuce canoe 

When your turd lays on the bowl, goes down into the water, and then comes back out of the bowl like how a canoe floats on water.

Jim: A....what?
Tom: A massive deuce so big that needed its own paddle.

Deuce Canoe 

A play on words of "Douche Canoe," which Oxford dictionary states is: an obnoxious or contemptible person (typically used of a man). "Deuce" doubles down on the douchey-ness by multiplying the abhorrent behaviour by the factor of 2.

"This deuce canoe from Facebook Marketplace tried to use children's items to prop up his scammy ad."
"Tucker Carlson could float on any liquid surface because he's such a massive deuce canoe."
