Top Definition
An ex-boyfriend who shows up at the wierdest times and places despite the fact you broke up with him over a year ago and haven't spoke with him or attended the same school or live in the same city. Creeps you out. Never seems to leave your life.
Melissa: Hey, let's go over to HotTopic.
Stacy: No, wait, there's my ex-boyfriend standing over there.
Melissa: Again. He was here last time.
Stacy: I know he's a Ghost Bo, he haunts me.
Melissa: Creepy.
