When you find someone doing porn who looks just like a friend, but said friend insists it isnt her rubbing one out on her webcam (though it probably really is)
"Hey is this (insert whatever porn website mysteriously popped up on your computer) you"
"No!"
"Are you sure?"
"Yes! It must be my dopplebanger. Why are you looking at asian porn?"
"Um.... got to, I have a phone call. fapfapfapfapfap"

Dopplebanger
(n.) a guy who gets girls drunk and then has sex with them (usually in a darkened room) while pretending to be their boyfriend
Someone who looks identical to your previous or current girl/boy friend, and you want to bang/date them. A rebound that looks exactly like your latest partner.
To get back at his ex girlfriend, he decided to date her Dopplebanger. His new girl looked physically identical to his ex. Let the drama begin.
