A keegan tries extremely hard to include to impress people, completely clueless that everyone hates them.
Person 1: "Hey, should I get that popular kid a birthday present?"
Person 2: "Why? He hates you"
Person 1: "No way, we're so tight"
Person 2: "Don't be such a keegan"
Someone so fucking annoying. They always fucking follow you, talk extremely loud, and have terrible voice cracks. Sometimes they are too nice which makes you want to die. They don't understand personal space. And are overly attached to the person they like.
