For maximum impact, the turd should be a solid.
Diarrheal coinstomping is a whole different practice.

The percentage of people interested in the coinstomp fetish has greatly increased during the past 2-9 years

While Tofundi was dreaming about unicorns and the delicious taste of the rainbow, I tenderly coinstomped my fermented shit into his ass.

clownstomp

To utterly humiliate someone and insult him/her (calling him/her a clown) at the same time. This is a variation of the word curbstomp but is slightly more humorous.

Alternative definitions may say that the victim was humiliated so badly it is as if he was stomped on using clown shoes.

Ashlee Simpson got clownstomped by her band on SNL.
