Undercup 

When a female reaches between a man's legs from behind to grasp his cock and balls.

As I was leaving the party I was surprised to receive an undercup while in mid-step. Unfortunately, when I turned around she was built like an offensive lineman so I ran away feeling violated.

Undercut 

A strategic move in racing to get past the car in front without actually overtaking it on track. The car behind will pit earlier, do a quick lap on fresh tyres and come out in front once the other car has pitted.

Commentator: 'Red Bull are pitting this lap, they might be trying to get the undercut on the Mercedes.'
