Roller coaster shit

The actions and emotions a person shows when they are on the toilet and trying to shit something big...and it hurts. Similar to the emotions and actions while preparing for a roller coaster dive with the rejoicing hand raise at the end (woohoo!).

I didn't shit for days but when I did it was a roller coaster shit!

Tokyo Roller Coaster

(N)'Tokyo Roller Coaster' is the name for the process of defecating into someones japseye. It is mainly performed as a sexual act, celebrating the art of sodomy by the unorthodox reversal of each orifice's role.
However, the japseye may also function as a temporary waste repository, if it is sufficiently cavernous.

The name is derived from the reference to Japan in the term 'Japseye', and roller coaster is a reference to the rapid decent of undeposited feces towards the ground.

Isn't it funny how you always find a kernel of corn inside it, after being performing a Tokyo Roller Coaster?
