Abrv. BMS. The frequent and potent finkel air excretion caused by ingestion of large amounts of beans and bean biproducts. Most commonly caused by excessive burrito intake. Syptoms can last for several days and can include diarreah, motorcycle-like sounds, and a trail of rank gas potent enough to clear even the largest of rooms.
"My friend is BMS'ing because he can't keep his hands off those damn Grandito-Burritos!"
White Girl: "Last night my parents totally had a beanervention with me. They think I'm going to marry a Mexican."
Friend: "So does that mean you can't go to the swap meet on Sunday?"
A yearly hockey tournament between boston university, harvard, northeastern and chestnut hill university (more appropriate name for boston college). Boston University has won more beanpots than the other three schools combined.
