A modified version of the Emeril. To ejaculate semen into the palm of your hand and hold it in front of a sleeping person's face while yelling "BAM!" thus making them spring up into it.
An event of immense and epic proportions. LANGASM is a Local Area Network (LAN) party that is so epic and grand in nature that the phrase "LAN party" is no longer sufficient. The anticipation of this event could cause spontaneous copulation simply from thinking or planning the event. Set up should never be done the day of the LANGASM. For example see nOObs. This day or days must be meticulously planned and executed. Second rate items such as food, drinks, entertainment, other essential party supplies and annoying friends are strictly prohibited. Naps are permitted, but sleep at your own risk. Your score and/or hair-do may be adversely affected. L337 speak is encouraged, but it is never ok to say "I shot him with my gun" while playing a FPS (First Person Shooter) game.
The USMC drill sergeant has just woken up an oversleeping cadet by setting off the Lagasse alarm, throwing pepper on the man's face.
"BAM! Wake up, maggot! Just who the hell do you think you are? Rip Van Winkle? Get up, take a shower, dress up, and catch your sorry carcass up with the rest of the others who are apparently better evolved primates than you are! Yeah!"
