Meaning

A no-good guy or loser boyfriend — a man who is unreliable, unemployed, unfaithful, or otherwise unsuitable as a partner.

ダメ男 describes a man with clear flaws as a partner: he might be chronically unemployed, irresponsible with money, unfaithful, emotionally manipulative, or simply lazy. It's often used when friends warn each other about bad partners. The female equivalent is ダメ女 (dame onna). The concept is a staple of Japanese relationship advice and media.
