A turd assault is when you go to take a crap, but all that comes out are turds. There is an absence of any long pieces of poop, and only short, round turds are present. Usually dissapointing for any male to experience.
My last toilet visit was just a turd assault. What a rip...
The result of accidentally or intentionally scooping one or more pieces of shit out of either your ass or someone else's ass with your fingers. Usually done in a sexual act.
Any removal of shit from an ass other than the normal grunt-and-push method.
