The greasy teabag

This is where you poop your pants with a very soft stool, then walk and sit and stand enough to smoosh the load all over your genitals. Now drop trou and proceed with standard teabagging proceedures.

After eating way to many prunes and way to much spaghetti, little Johnny had a unfortunate ( but opportunity rich ) loss of bowel control while dressed in his Sunday best. He then decides to make himself feel better by giving his drunk and passed out older brother ( who is normally quite mean to little Johnny ) "the greasy teabag".
