look up anything, like your first name:
1. emergency blowout liquidation
Originally a term for a discount furniture sales, the term was aptly and readily converted to describe a bad case of violent diarrhea.
After eating street tacos in Tijuana, Scott implores to Jef to pull over at the next gas station;

"Pull the fuck over dude, I've about to have an emergency blowout liquidation!"

Or in a more formal situation;

"Pardon me, I am about to have an EBL and ruin my tuxedo pants."
