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

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.

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.

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.
A: DAMMIT, I got a bad case of backdraft!
Q: What happened?
A: I tried to fart but it crept back inside because I didn't force it hard enough. Now I'm all bloated and constipated-like.
