Gae/Gey
Gae is when someone is so smart they make your brain feel like it's been hit by a brick. It's not just bad, it's educated.
Friend: 'I got an A on the history test.' You: 'You're gey.'
Text from mom: 'Why did you get a D? You're gey.'
Classmate: 'You're gey for not knowing the difference between a novel and a biography.'
