toxic masculinity is referring to overcompensation for a lack of traditionally male-associated values, like honor, responsibility, etc. the complete lack of those values manifests often as toxic masculinity:
avoidance, anger, entitlement, distorted view of reality, inability to rationalize normal behavior, victim blaming, disrespect of women (or other groups considered outsiders), preying on weaker people (or use of violence/weapons to confront problems because they otherwise feel helpless), etc etc
