Having shit in your pubic hair
"Sorry I couldn't meet up with you on time, I was in the bathroom for an hour, sorting out my curly wurly."
The act of rolling up ones flaccid penis and tucking it against your balls to create the effect of a snail shell.
"Which way do you stick your dick down your trousers in the morning, the left leg or the right?"
"I just give myself a sneenis and get going."
