Refers to the way men think in regards to their lack of finesse and attention to detail in general; particularly, though, in socially sensitive ones. Much like using an ax instead of a scalpel to dissect, or a shotgun instead of a sniper riffle to shoot a target.
Anyone exemplifying the man-brain lacks the etiquette to handle delicate or intricate social situations as wells as critical thinking that requires consideration for all the problem's aspects.

When a son tells his mother to move her feet so his girlfriend can sit in an effort to "act more like a gentleman" as the mother has been advising him to do. The son is showing a clear case of man-brain.

You: I've been working for hours and can't figure out this homework! It's too difficult, why would they give us something that's impossible to learn?
Friend: Dude chill out you just have a massive brain erection. It needs to go limp, just go play with your pet squirrel for a bit.
(Later)
You: Hey this homework makes sense now!

The feeling you get when you are having a lively discussion or listening to an engaging lecture and everything makes sense and it gives you a bunch of new ideas about the topic at hand. The intellectual equivalent of an erection.
DeSean: oh man, that lecture given by Dr. Kobilka about G protein-coupled receptor dynamics gave me a massive brain boner.
Derrick: uhh...right, yeah, totally dude. *pssst* Jimmy, I think we need to re-evaluate our friendship with DeSean...
Jimmy: agreed.
