Abbrv. of Girls at the Back
Composed of unusually tall girls seated at the back of the room, with an abnormal sense of humor and wit. They usually get in trouble for being too loud during class because they talk like their half deaf.

Poor attention span and focus. No two members are ever the same. They are generally labelled as 'out of this world'

A peculiar group who would prey on the unsuspecting, engaging them with random topics that are generally about nonsense. They never leave you until they're satisfied, or if they get distracted with someone else
"Hey, it's the GATB!"

"They're awesome. But! Better not get their attention. They'll never leave you alone"
