A large, smell, big fat turd.
Who left a poo-cumber in the toilet?

A long fat green turd. Usually found after a heavy night on herbal spirits (jagger bombs, etc.)
Ah mate…that was a heavy night on the bombs…I think I just did a poocumber!

A crap so big it looks like a cucumber. Doesn't necessarily have to be green.
I just took the biggest dump in your mom's bathroom, man. We're talking one poocumber after another!
