Doppelnamerbanger 

A person who has sexual intercourse with someone else that shares the same first name (closely related to a doppelbanger).

Hey Sam, did you end up tapping that chick last night you met at the laundromat?

Yeah, it was sick cuz I got to scream my name the whole time without any serious recourse. Quite a doppelnamerbanger episode, I must admit!
