trapdoor

During the inhale or exhale process of smoking a bong or other devices, a trap door occurs when the flow of air is stopped abruptly by a cough which constricts the wind pipe to the lung. This traps the smoke inside the lungs and causes extended exposure, resulting in temporary distress to the user's throat and/or lungs.

John: *sinks a bong, holds breath, then coughs all the smoke out*
Dan: LOL John just trapdoored

Trapdoor

The act of disappearing during a drinking session due to too much drink/lack of money/boredom/avoidance of forfeit without letting anyone know.

They were starting on the dodgy pints and penalty gins so I trapdoored last night before it got too messy.

trapdoor sandwich 

A sandwich so jam packed that when you take a bite everything falls out of the bottom through a massive hole that spontaneously opens up.

trapdoor booger 

A booger that is trapped in one’s nose, usually stuck to the wall of the nostril, which flaps back and forth like a hinged trap door when breathing. The trap door should be removed with caution; if snorted too vigorously when trying to loosen, it may suddenly release, resulting in being sucked down into the back of your throat, Which may induce nausea or vomiting.

I’ve had a trapdoor booger stuck in my nose all day, It’s driving me crazy!
