Slut Double 

A woman that looks like a celebrity (actress, model, musician, pornstar, etc.).

My girlfriend is Alexis Amore's slut double.

I was fucking Jessica Alba's slut double the other night.

I like to fuck slut doubles since the real thing is out of my league.

double dining slut 

Somebody who makes it seem like a special thing that two couples have dinner together when in reality they are just cycling couples like slot machine.

Those guys are a double dining slut.
