A bullpup submachine gun manufactured in Belgium by Fabrique Nationale. The P90 is prehaps the most versitile weapon of it's kind: It's 5.7x28mm round possess better ballistic capabilities than the 9mm, with greater range and armor penetration. However, due to the uncommon round and doubtless high expense, the 9mm SMG will be around for a long, long time to come, which is perhaps a good thing, with guns like the Heckler & Koch MP5.
Dr. Evil cursed his cheap gun and picked up a P90, only to be eaten by his own laser beam-headed sharks, after the frikin' thing jammed.

The simultaneous use of the P90 submachine gun and rushing (the act of quickly attacking your enemey before they have a chance to prepare)

While it is mostly found in Counter-Strike Source this technique can be extrapolated into real-life situations with imaginary weapons and enemies. The objective is to reach your target while using imaginary flashbangs and smoke grenades. You are not allowed to be seen. If seen you fail the P90 rush. Enemies are commonly found to be parents, siblings or room-mates
Gamer1: I'm going for a P90 rush, wanna join me?
Gamer2: sure, I'll buy a few flashes

person1: Wanna P90 rush the kitchen for some hula hoops?
Person2: Yeah, I'm famished *loads imaginary P90* Alright, lets move out

The RC-P90 is called P-90 in real life. The real gun only contains 50 bullets per clip. It is extremely agile, light, and rapid fire. It may be the best gun ever made but it's probably the most expensive.
The goddamm squirrels are making a home out the hole where the wall meets the roof; I'll show them just how welcome they are with my RC-P90. I hope I'll blast their little brains out with all of these bullets.

CoD 4 player who sucks unless he uses a P90 submachine gun.

If he runs across an enemy he will shoot first no matter what.

Other players will insult him because P90 is considered a cheat gun since it is good at short and long range, with or without aim. It has also a very good fire rate.
P90 guy playing CoD4 kills 7 people in a row:
-Got the choppa!
Player killed:
-GTFO P90 n00b.
