Back Fire 

That fucked up half-choke/snicker sound you let out when you took too big of a hit, but then hang onto it...

Back Fire is the action like in Up in Smoke, when Cheech hits the Maui Wowie Labrador joint, and Chong tells him "Toke it up! Toke it up man!"

Brown Eye Back Fire

A Brown Eye Back Fire is when you take a dump and when the poop hits the water in the toilet it splashes up on your butthole. It is the most disgusting feeling in the world that everyone you’ve ever met has experienced.

Guy on toilet: “(splash) AHHHHHHHH”

Guy’s wife: “What’s going on in there?”

Guy on Toilet: “Fucking Brown Eye Back Fire.”
