Judge Dredd is a fictional character who appears in British comic books. He first appeared in the second issue of 2000 AD (1977), a weekly science-fiction anthology. He is that magazine's longest-running character.  Dredd is a law enforcement officer in the dystopian future city of Mega-City One in North America. He is a "street judge", empowered to summarily arrest, convict, sentence, and execute criminals.

In Great Britain, the character of Dredd and his name are sometimes invoked in discussions of police states, authoritarianism, and the rule of law.

Dredd was popular enough to be the basis of a mediocre Sylvester Stallone film, and an excellent Karl Urban adaptation.

The intricate science-fiction future world included the creation of appropriate futuristic slang, including curses.

Grud - an object of worship by the inhabitants of Vatican City, it is usually used as an analogy to God (eg. "Grud Damnit!").

Stomm - an unpleasant substance (eg. "What is this stomm?").

Drokk - a profanity, it is used most commonly as a verb (eg. "Drokk it!" or "You little drokker!" ) but also an adverb (i.e "Get the drokk down!").

These buttons are entirely appropriate addendums to your mutant biker gear or your iso-cube garment; but I bet there's a law about wearing any of them on your Judge uniform.  NOT bulletproof!
