This isn't meant to be some crazy 500k damage move or something; it's just an easy way to rip Uke's arms off. (I don't know if this is old or not, since I just started playing this game a few weeks ago.)

Relax all.
Space x3.
Press C.
Contract pecs.
Extend glutes.
Grab hands.
Space x2.
Hold glutes.
Raise shoulders. (This is optional. I did this so I wouldn't get hit by Uke's loose arms.
Press P.

Simple, yet somewhat bloody. Enjoy.
