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".

Coworker 1: "Can you assist us with this project? We need everybody's help, because there's a ton of work."

Coworker 2: "I'm really busy right now. Kind of overwhelmed."

Coworker 3: "Bullshit! All you're doing is IMing your friends. It's pretty damn obvious by your constant machine gunning. Now do your frikkin' job."

I really needed to crash because I had the spins from partying too hard, but I was kept up all night by my herb of a roommate machine gun typing to girls he'll probably never meet in real life.

machine gun flatulence 

That sudden and startling, very loud rat-a-tatting that exits as you lean forward in a quiet restaurant.

I thought we were being targeted by a cartel for a moment but it was just my grandfather’s machine gun flatulence.

Machine Head 

1. /THE/ Gods of metal music, although they let themselves down with the albums where they experimented with their sound, namely The More Things Change, The Burning Red and Supercharger (which admittidly contain good songs). Found retribution with the almighty "Through the Ashes of Empires".

2. The pegs on your guitar's headstock that you use to tune your guitar.

3. Band that features the legendary Robb Flynn. Who is in turn the god of all metal.

1. Holy fucking hell have you heard Imperium by Machine Head? They are truely teh gods of metal!

I can't wait for Machine Head's new album, it will fucking own the big one!

2. I like to keep my guitar's tuning pegs nice and shiny with a good polishing every so often. Ohhh yes.

3. Robb Flynn > You

Machine Gun Kisses 

A series of quickly delivered kisses due to time constraints.

Machine mode

When a male goes to a social gathering (such as a bar or club) and tries to chat up every female at said gathering.

A male in machine mode who gets knocked back by a female, will quickly forget about the female and move on to another female, often the nearest female to the first female and probably the first female's friend.

Friend 1 @ a club: "Alright mate, where you been for the last hour?"

Friend 2 @ the club: "No time to chat, I'm in machine mode tonight, I've already been knocked back by half the girls here... time to move on to the fat chicks. Later."
