During anal sex with girl friend the man spits on her back so she thinks he jizzed and when she turns around he jizzes on her face and she makes a pirate sneer.
When you write gay on your hand with chalk and then apply your hand to the jacket or sweatshirt of another it will imprint a the word "gay" on the jacket or sweatshirt.
Make sure your write it backwards, for if you don't you will have "yag" written on your fellow friend.
