Toilet Snooker
Only possible by a male, 'toiler snooker' is the occurence while defecating of hitting ones testicles with a stool which is curling around past the gooch; similar in action to that of a snooker cue on a ball.
"Why are you taking so long honey?"
"I'm playing toilet snooker darling!"
"I'm playing toilet snooker darling!"
