iMumble - (EYE-muhm-bul) n: The drunken, trailing sentence issued by a person who has stopped paying attention to you and has become engrossed in some small electronic device.
This typically happens in a lunch setting where an individual who was involved in a conversation has suddenly been buzzed, beeped, shocked, or prodded by an iPhone, Blackberry, videoWatch, or subspace communicator, and attempts to continue conversing while reading.
Many thanks to Andrew Kelley at lunch today for his addition fribble labbel zzm... .. . .
