Another name (euphemism) for a shit stirrer. Back in the day when folks used outhouses, they often had a stick used to stir in lime or other things, often called a pudding stick. Also related to "stirring the pot."
Is a term used not only for a desert but also to describe a poofters or womans arsehole after a guy has blown hes load inside his/her arse and the cum oozes out.
When you cum every where in the shower and get cum on your leg but don’t realise until you get to school and your leg hair is all sticky and tangled up in knots
What’s that on your leg? Oh Um (looking around nervously) just sticky pudding cunt
