when you have a girl all over you and you dont like her, it gets the girl off of you.
you have a girl on you touching you. You don't like her. You then simply state to your friend "code D". He then walks away a small distance, and says "hey (Justin) i need to talk to you". you then proceed to persue a conversation with your friend, away from the girl. you fake a conversation, and when you return, you choose a different place to sit. This place to sit is away from the girl that was all over you, you can use this trick multiple times.
