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.

A fart in bed that is released prior to your parter getting under the covers. The gas from your fart is trapped within the tighly tucked sheets and no smell is able to escape. When your partner goes to get into bed, they untuck the sheets, thus allowing the trapped stench of death to escape into the fresh air and blast them in the face.

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

When smoking marijuana, a person can take a hit too deep, which burns the back of their throat. They then hold their chin against their chest, thus holding the burning sensation down. Eventually this sensation seems to "burn itself out," like a real fire deprived of oxygen. However, also similar to real fire, when you raise your head and open a passage for air, the burning "flares up," like real backdraft.

When you attempt to fart, but not enough effort is exerted so the gas bubble creeps or is suctioned back inside. You end up having to wait until it re-forms before being able to expel it.

The uncontrolable suckback of air associated with chugging a carbonated drink too fast.
