This term was first used by Kebab and Prangle It came to be as the two of them were bored as shit at a lake (Skorzęcin, Wielkopolskie,
Poland) , and decided that "Schruckers" was funny, and now became a term for literally everything, but mostly a humoric
way of saying, EEEE, what? Or it could also
mean an expression of sadness after, let's say dying. You can also use it as a adjective, or a verb,
