Toxic masculinity
Toxic masculinity is an excess of behaviors that are perceived as being masculine. Among these are predilections towards conflict, domination, and sexual conquest.
Individuals who succumb to toxic masculinity often become obsessed with fighting, guns, and treating women as resources to be controlled rather than as complete human beings.
The concept has been poked at through the comedic films of Will Ferrell (Old School, Stepbrothers, Anchorman), among others, who depict characters so hypermasculine that they verge on ridiculous.
Toxic masculinity has been blamed for many things including war, environmental degredation, bullying, and mass shootings.
