OBD
OBD is when a girl likes a boy so much she can’t stop following him. He probably thinks she’s a stalker, but she’s just being obsessive.
I’ve been following him to school, the grocery store, and even his dog’s park.
She likes him so much, she followed him to the gym and now she’s part of his workout routine.
He said he’d never come back, but she followed him to his house and won’t stop texting him.
