OBD
OBD is the advanced version of a girl who is obsessed with a boy and won’t stop following him. It’s like the final stage of being a stalker.
She followed him to work, then to his lunch break, and now she’s at his apartment.
He’s been trying to ignore her, but now he’s stuck with OBD.
She’s been following him for weeks, and now she’s got a job at his workplace.
