1. an extremely long pause during a public announcement over an intercom, where the microphone is still keyed and making static noise, indicating a brain fart by the person making the announcement.
Bruce was very nervous on his first day as a stewardess. While making the the safety announcement, he slipped into an "intercoma" in the middle of explaining the oxygen masks.

For nearly thirty seconds, the microphone hissed in the passenger's ears until he regained his train of thought.
