When you are smoking some herb out of a bong and you take a large hit and unexpectedly cough with your mouth still attached to the bong, causing water to rush up and into the bowl, effectively ruining all weed in the bowl and putting it out, while also making all your friends very pissed off at you.
Jon : "I'm passin':

Jon hands the bong to Gary, someone who's new to the smoke.

Gary hits the bong

Gary : Bong regurgitation

Jon, Lawrence, Alexander and James are now very pissed off. Gary is ashamed.
