When having sex with your girl, and your pants are by your ankles. Having sex quick without getting undressed.

Get the Half Windsor mug.
Noun: When your balls feel like they are twisted after getting off of a plane and paired with jet lag. Can also happen after a long road trip, and your legs fall asleep in your car.
