crowd farting

The act of walking into a group of strangers and dropping a particularly heinous fart, especially humorous when done on an elevator; usually done as a vacation activity.

Example 1:
Jessica: Why's it smell like dead bodies on the elevator?

Terrence: Alex and I were dropping crowd farts the whole way up.

Example 2:
Jon: Why are you drinking all that milk before the concert?

Chris: I'm going to try to set a crowd farting world record.
