真面目系クズ
Significado: Someone who looks serious and responsible on the outside but is actually lazy, unreliable, and useless.
真面目系クズ describes a person who gives the impression of being diligent and dependable — they show up on time, dress neatly, and don't cause trouble — but in reality they cut corners, coast on others' work, and avoid real effort. This gap between appearance and reality is what makes the label particularly biting. It became popular on internet forums and social media as a self-deprecating identity.
