Doppledonger 

When you find a penis that is an exact match to your own. Like twins separated at birth, but attached to a different person.

I was giving head to this guy, and it felt like i had seen his dick somewhere before . I realized it was MY dick. If i suck my doppledonger, isnt that like giving myself head?

Doppledonger 

When one finds a male sexual partner who's penis is identical to one that they have encountered with a different partner.

After last night I can confirm that Devin is definitely Seth Rogen's doppledonger. Those penises were identical.

dopplefanger 

1) The exact look-alike vampire version of person. NOT an exact mirror image version because vampires have no mirror image.

2) True Blood meets How I Met You Mother

That girl with the monkey bite on her neck is telling everybody she was bitten by my dopplefanger.
