Be me 

At a party with my gf

Having a great time, enjoying that new beer I brought over

Suddenly I notice my gf across the room, giving me looks to help her

I walk over, some dweeb taking about his latest hentai obsession it some weird shit 

Being a couple drinks in, I try to let him know that he's making my gf uncomfortable with his behavior

Fuck it, maybe he's cool, I offer him one of my beers, let's get to know each other

Out of nowhere here kicks me in the balls. Wtf.

Host apologized to me and kicks the guy out.
