You now have to do what you said you were going to do otherwise your nickname is girldick for the rest of the day/week/month/year or even the rest of your life - depending on how bad the girldick is.
However girldicking can be blocked by saying "no girldick" before someone else says "no you wont girldick"
Fred: No you wont girldick.
John: Haha, im going to go ask out Mr's Jefferson
Fred: No you...
John: No Girldick
