1).A turd comprised with chunks of undigested food such as corn

2).Multiple turds from different donors stuck together, usually found in port-o-pottys and gas-station restrooms
"After eating that corn today, next time i shit there's gonna be a huge turd mongrel in the toilet"
Get the turd mongrel mug.
Why did you search this. Seriously what are you like 80? Who even says that? I feel bad for you and anyone you say that too. Honestly if you want to want to use an insult made by the queen of England why don't you say something like bloody fool or something.

Sonny boy: *leaves*
