Fart Hostage

(n) : a person who has the unfortunate fate of being in a confined space while someone passes gas. This can occur in a car, elevator, subway, or city bus, for example. The person(s) in that confined space became the flatulator's fart hostage(s) for the duration, until the fart haze dissipates.

"Man, Henry is not allowed to eat beef jerky on long car rides anymore. He was beefing nonstop, and held us fart hostages all the way to Kalamazoo!"
