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.
