Machine Gun Typing

Rapid stop and go typing that one does when instant messaging. Can be identified by the tell tale sounds of: tappity-tappity-tappity-tappity-tappity-tap-tap-tap-CLICK *pause* tappity-tappity-tappity-tappity-tap-tap-tap-CLICK *pause* tappity-tappity-tap-tap-tap-tap-tap-tap-tap-tap-CLICK and so on... Named because it sounds like and has a similar rhythm to firing an automatic weapon. Usually not that annoying, but can be incredibly irritating when done by that lazy co-worker always slacking off at work or that college roommate that IMs until 5am every night. Also known simply as "machine gunning".
