Jack-hag
A Jack-hag is a woman who sees every Michael Jackson lookalike as her soulmate and will do anything to date them.
She asked the guy who did the dance at the restaurant if he wanted to go to prom with her. He said no.
She followed the guy in the grocery store wearing a Jackson shirt. He bought a sandwich and ran.
She tried to text the guy who did the moonwalk at the bus stop. He blocked her.
