Cuban Fatboy

An enormous, solid bowl movement that settles in the toilet pan without breaking thus resembling a huge Cuban cigar.

Archibald: Wow, do I feel better now!

Cyril: Why so old chap?

Archibald: I just curled out the most monstrous Cuban fatboy you've ever seen. The tip was poking out of the water it was so big!

Cyril: Huzzah!

Archibald: Huzzah!
