When a male, ages 13-33, sits in a tub with only the head of his dick petruding from the water proceeds to rip off the wings of a common housefly and then allows the fly to run around on " mushroom island". For ages 34+ its known as the Castaway, or Mr. Wilson.
I was using the bathroom at wes' house when i noticed the pile of fly wings next to the tub, i felt compelled to confront him on his addiction to the mexican fly.
Paulsen got caught by his wife in the middle of a mr. wilson. Water went everywhere.
