look up any word, like donkey punch:
This is a when you used a socked foot to rub your girlfriends labia while sitting in a public place.
The Conrad can be used while attending a class with your girlfriend sitting across you, you slide your foot between her legs and begin rubbing her vaginal area.

"She wanted me soo bad during class, I had to pull the Conrad just to keep her happy"
