whoopee cushion

Noun

 * 1) An inflatable bag containing a valve at its neck that retains the air in the bag until pressure is put on it (usually by someone unintentionally sitting on it after it has been placed on a chair by someone else as a practical joke), when the air is expelled with a sound similar to that of someone farting (breaking wind).
