steamy cartwheel

A person standing up takes hold of another person upside down in the standing 69 position. Both people move their heads as close to the other anus as possible before taking a shit and attempting a cartwheel.

Joe: "Garry you fancy being upside down this time in the steamy cartwheel"
Garry: "Only if we are quick, it isn't comfortable"

Krappen

A monster of a turd that can only be compared to the legendary sea beast The Kraken.

Woah man you should have seen that three headed turd I just did. It was an almighty Krappen!
