Dick Glance
When a man removes his penis from his pants while his partner is not looking during a makeout or lapdance or similar pre-coitus situation. Upon seeing his penis, the "glance", there is a 2/3 chance that the partner will act favorably on the sighting. aka "The DG"
When we were in Vegas, Jack pulled the dick glance on a stripper. She took the bait. Good thing we were on separate trips.
