When you are on the toilet but the toilet seat is colder than your butt.
"Dude i was taking a cold shit and I couldn't even touch the toilet."
"Yesterday my friend took a cold shit and his ass stuck to the toilet."
"As soon as i put my ass down i jumped off the toilet cause it was like a cold shit."
Some seriously cold, unfeeling, shit.
Girl 1: Sorry, but I have a three inch minimum.

Girl 2: I have a nine inch minimum.
Guy: That's some cold shit.
