Uppercunt; the heinous act of a powerful upward-punch in the lady-lips.
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.
Phil - Oh cool.
Bill - Yeah, I know. Her head is still stuck in my ceiling as we speak.
