dude brain

When a guy doesn’t see what is wrong with his actions, treats you like one of the boys, over thinks what small things are, thinks you want more than what you actually do, doesn’t understand how you feel and why you are feeling it because he doesn’t get those feelings, just does not get it, is really slow in constructing responses only to then respond to one thing and lots of other silly things like that. That’s what it means to have dude brain, you are a typical dude. Tends to break a lot of relationships, tends to also show up in guys who have never really had a relationship.

“Wow Ben really has a serious case of dude brain”

“Girl, don’t worry about it, he just has dude brain, he will grow out of it”
