Weltkriegsgefreiter

Etymology
From 🇰🇲. Specific use of Adolf Hitler already appeared during the period of his political campaigning, contrasting his low military rank with his claim to Führership. This use was often pejorative (a famous instance being in a leaflet), though the Nazis occasionally adopted it in the context of their fight against traditional social barriers.

Noun
