A double ganger
A double ganger is when you’re having wild sex with two people who look exactly the same and you don’t realize they are two different people. You just think it’s a weird group thing.
I had a double ganger party and ended up with three people and no idea who I had sex with.
My friend said he had a double ganger and now he doesn’t know if he’s in love or just confused.
I went to a double ganger and I thought I was dating two people, but it was just my ex and my cousin.
