When a driver (a middle aged or older woman named Gail) is getting too close for comfort behind another on the road. When the driver hits you, she will arrogantly assume she did nothing wrong as if Gailtating isn't illegal or dangerous.
Innocent driver: WTF, this bitch won't get off my ass!!

Passenger: Fuck, someone's Gailtating you again, switch lanes before she rams you at the red light.
