A similar species to the wehraboo or the tankie, the Goobus is the kind of person who thinks that Blue-haired pronoun-havers are all that’s wrong with society, or that the world would be better if the Nazis won. The Goobus can usually be found at talking about why a certain dictatorship or imperialist regime is/was the coolest and the best.
The sort of thing you'd call a silly or adorable thing, like a cat doing confusing things, thus making them goofy, and lil. Earning the title, "Lil Goobus"
