I think axiom should fit, but according to its official definition, an axiom is a statement that is taken to be true, and as far as I know, a word can’t make an statement by its own.

      The definition of crack in that instance would be something along the lines of: “The snapping sound the air makes when creating a small sonic boom. Like that of a whip cutting through the air.”

      Even onomatopoeia has synonyms. Like some people say Atchoo. Some say kerchew. And then other languages say other words for the same sound.
