1 عمومی:: ادم خوش نیت ولی احمق وبی عرضه
شبکه مترجمین ایران
1 general:: A singularly inept person, as in Poor George is a hopeless sad sack. This term alludes to a cartoon character, Sad Sack, invented by George Baker in 1942 and representing a soldier in ill-fitting uniform who failed at whatever he tried to do. It was soon transferred to clumsily inept civilians.
