What is G4 Haircut?
1.
The act of shooting G4 (or anyone annoying) in the top of the head, resulting in hair being blown from their scalp. It can be done with your "Telly Gun" (2 fingers you point at the telly in the shape of a gun, when an annoying, cheesy advert comes on or someone that you really don't like.)
