Unpercent 

The process of converting a percent back to a fraction. Blood may or may not be involved.

Nick was sweating and bleeding in the lab after confusing 0.01 with 1%. Daniel made him unpercent his numbers and pursue a degree in Electrical Engineering instead of being a Math major.

Uppercunt 

Similar motion to the uppercut. The only difference is location.

Not to be mistaken with fisting, which is very similar. The difference being that the Uppercunt is fast and not a repeated motion as there is no need for further pleasure after such a maneouvre.

A technique that is apparently associated with Leeroy Jenkins.

Bill - Last night I got my Uppercunt on.
Phil - Oh cool.
Bill - Yeah, I know. Her head is still stuck in my ceiling as we speak.
