When you live in close accomadation with friends and you're having sex with a girl, before she is about to come, you shout "Mortal Kombat?" and your boys shout, "FINISH HER!!!"
through the walls.
Mortal, meaning can die, and Kombat, meaning -well- to fight.
Shao Kahn, Shang Stung, GOro, Kintaro, Quan Shi, to name a few well know 'bad guys' in an epic game that has given birth to a whole new genre of computer gaming! Without it i would curl up into a little ball and weep...
