When a person (usually a teenager) shits their pants in a watery and explosive manner to escape a drug test appointed by his or her parent or legal guardian changing the color of said person's pants and floor causing a literal shit storm

Drop a deuce, make a bowel movement, take a number 2. Along the lines of drop some kids off at the pool, have a brown baby boy, etc. Created by yours truly after watching a particular South Park episode.
