i.e. Medicine: Medical jargon would be a complicated diagnosis or term used by a doctor nurse or someone involved in the medical community. Jargon is typically used by douchebags who think they're hot shit by knowing words you don't, when in reality they are just gay.
Person 2(douchebag): Ahh, you mean your cranium.
Person 1: Don't bring that shit here, throwing down some straight up medical jargon.
(marine 2) Hey! don't use that jargon around me.
