The word marklar stems from an alien race named the Marklars, which appeared in an episode of the animated series South Park. The Marklars use the word marklar as a generic word, similar to a pronoun, that can refer with specificity to any thing, place, person, idea, concept, or otherwise represent the meaning of any noun, including proper nouns.
Marklar: "You see, young marklar. Those marklars don't care about marklar marklar. They just want to take your marklar and marklar their own marklar. The only marklar for this is to marklar."
