nice guy syndrome
/naɪs ɡaɪ ˈsɪndrəʊm/
CommonA behavioral pattern where a man suppresses his own needs, performs kindness, and expects romantic reward, becoming resentful when it does not come.
The 'syndrome' framing treats it as a pattern to be unlearned, not just a personality type to be mocked. It has a self-help literature tradition alongside the internet mockery.
