The shape that a gaming headset or any type of over-the-head headphones makes in your hair after a gaming session. This shape can also occur when you are listening to music for a long time without taking the headphones off. This usually occurs in people with shorter hair
Gamer: I didn't take my headset off for four hours and my hair got a gamer's gap
Gamer 2: I hate that bullshit it makes me look like an upside down cereal bowl!!

Yeah man, she's a three-finger, no doubt.
