Backdraft 

The odor cloud that hits an unsuspecting person when they open their office door after a co-worker has farted in it.

"I now always stick my nose under my office door and check the air, as to avoid being the victim of a backdraft."

Baltimore Backdraft 

This grotesque act takes place when one individual deficates into the funnel while the other individual blows into the tube at the end of the funnel. When the feces is blown back to the other partners anus, it is known as the Baltimore Backdraft.

Due to her incredible lung capacity, she was able to send crap all the way to the ceiling, making me think twice before preforming the Baltimore Backdraft again.

backdraft 

An explosive surge in a fire produced by the sudden mixing of air with other combustible gases. This is caused by a condition in a fire where oxygen is depleted and the fire dies down until a door is opened and the fire flares violently from the sudden intake of oxygen. Backdraft can be described as a small explosion.

The most common tactic used by firefighters in defusing a potential backdraft is to ventilate from the highest point, allowing the heat and smoke to escape without igniting explosively.

blue dart backdraft

A "blue dart backdraft" can be fatal. "according to some questionable research." A blue dart on its own can be quite amusing. however if the conditions are just right, things can get ugly. A blue dart is when you lay flat on your back,(or for best results get on all fours). Pull your bare ass out, and hold any open flame uncomfortably close to your exposed anus(it might be easier to have a good friend hold the flame) and let one rip. the bigger the better. (great party trick by the way). but if your not careful you may cause a "blue dart backdraft". which is when the blue dart is retracted back into the lower intestine. igniting the remaining methane gas in your bowels. therefore essentially cooking your insides. until you die!

Dude, that blue dart backdraft almost killed me.
