Billie Jean instance 

when you're out and about and some girl you may or may not remember from the past comes up to you and is either pregnant or with a child. Then she claims that YOU are the father.

I was in a BW3 restaurant and this short stacked young blonde woman dressed in a black sweather, a short black skirt and black shoes called out my name and she came up to me with a baby boy and his eyes were like mine. Oh no. Who is that girl? Where did I meet her? This is a Billie Jean instance. It's just like the 1983 Michael Jackson hit.
