One who travels through the deepest depths of hell, in search of new jargon. Typically travels with other jargonauts, never leaves home without blank DVDs (in case "Mr. & Mrs. Smith could possibly be pirated off of someone they encounter on the way).
Has jargonaut lost his mind?
Can jargonaut see or is jargonaut blind?
Can jargonaut walk at all,
Or if jargonaut moves will he fall?
Is jargonaut alive or dead?
Has jargonaut thoughts within jargonaut's head?
We’ll just pass jargonaut there
Why should we even care?
