shit behind commentators

So my step dad is CONSTANTLY making jokes about my brother being gay, and it pisses me off. So, the other day this happened.

Me: “Mom, do we have any extra tooth brushes? I cant find mine and dont wanna try using my old one because i dont wanna mix it up and accidentally use Matt’s (my brother)”
My step dad: “Haha yeah you really dont wanna use his, we all know where his mouth has been!!”
Me: “Yeah, well, definitely wouldnt wanna mix it up with yours either on account of all the shit that comes out of your mouth on a daily basis”

That shut him the hell up
