Force XXI

Force 21

A revolutionary new type of training program being experimented with by the US Armed Forces, particularly the Army.

"Eventually when youngsters grow up to join the Army they'll be put through the Force XXI's VR simulations and stuff. It sounds better than live exercises, but is it good enough to train soldiers via videogames? Maybe, maybe not. I like videogames though. ^_^ "

Usually followed by laughter, especially when a particulary powerful shot connects with the face.

Ash: Did you see Johns awesome forced header?
Nat: Yeah, Paul smashed that at him
John: Ow...

fourier series

A sexual act involving 3 or more consenting participants in which they form a circle consisting of staggered 69 positions(running bricks). Each participant gives and receives oral pleasure from/to different parties.

Fourier series is able to be completed in either an odd or even form.

The professor helped the class through the Fourier series using hands-on examples.

I tried the Fourier Series last night it was really hard to differentiate between everyone but I think there was a model in there somewhere.
