A sexual act where one partner defecates on the second partner’s chest and urinates in their belly button. Then the first partner uses his/her penis as a paintbrush, painting a picture their chest with feces, and occasionally dipping their penis into the urine filled belly button like watercolor paint.
I had so much fun crainting on Uncle Jimmy's chest!
You have a cramp in your taint meaning you need to pass gas. Crainting is the same as farting.
“Yo dawg I need to craint so bad at the moment”
