老不死的屌丝

This is rather offensive language that translates into English as a derogatory term, referring disrespectfully to an annoying, often old-fashioned loser or nerd-like character who seems not to have much value in other people's eyes. Choosing such a self-deprecating pseudonym might imply humor, helplessness, frustration, self-mockery, sarcasm, or intentional anti-positivity.
