Boy brain

When a guy says some outworldly primal shit that can only be construed as an act of machismo.

This guy was telling me of how it's his dream to die in WW3. What kind of boy brain shit is that?

When a guy exhibits behaviors of a young boy whose frontal lobe has not developed even though they are at the age where it should be developed.

He has major boy brain. Why did he not think before he said something so stupid?
