Blow My Ass Off.

Occurs when ingesting extremely gaseous-causing foods or attemping to reenact the burrito episode from "Man verus Food". You feel like you are missing the entire lower section of your digestive tract. Treatment requires a visit to a digestive health specialist which may not be successful. On a postive note, you will be exempt from the phrase, "Stick it up your ass buddy" cause you don't got one!
