The Colon Cleanse is a complex sexual act that begins by inserting Mentos into your partners anus, convincing them that the candies are in fact anal beads. Once five or six mentos have been inserted, the male partner squeezes a bottle of Diet Coke into the female's rectum and plugs her butt with his erect penis. As the reaction between the coke and Mentos commences, the male partner must concentrate on holding his position for maximum explosion, and finally removing his penis from the woman's anus, releasing a whirlwind of Coke-Mentos-Feces-Ejaculate Fluid blend that effectively "cleanses" the colon.
MIKEY: My girlfriends flatulence have smelled quite fresh ever since we performed the Colon Cleanse last night.

JOSTON: Dude, I hope you put some plastic sheets down or something.
