GBS - Greasy Butthole Syndrome. A temporary medical condition that occurs when no amount of wiping can thoroughly eliminate the fecal remnants, thus lining the ass cheeks with a greasy or oily film.

GBS is most often caused when ingesting oily or greasy foods, such as pasta or cheeseburgers.

Sufferers often find themselves escaping to the bathroom intermittently throughout the day to take auxiliary wipes in an effort to find relief. Many report that the portion of undergarment that has cinched up between their cheeks has been coated with an unfortunate and yellowish smear.

GBS is easily cured by taking a warm shower and scrubbing the ass cheeks with a loofah and a liquid soap that has been fortified with exfoliating beads.

Those afflicted with GBS can also suffer from GBS Guilt. GBS often causes a tickle in the anus that is only remedied by a hearty finger scratch. One is often drawn to sniff their own finger in an effort to check for consistancy and aroma. This action often leads to temporary feelings of loathing, disgust, and self hatred.
After dining on a Diaper Burger and Chili Cheese Fries at the Tommy's Burgers in Long Beach, Tyrone suffered from a bad case of GBS.
