What is Jumped-up?
1.
Refers to someone acting in a really pompous, overbearing way, arrogant without any reason to be so, acting a fool or a jerk; the implication is someone trying to act way above their "station" or "caste", having "jumped-up" where they don't belong. Usually accompanied by an insulting noun. A term favoured by Gordon Ramsey on his cooking programmes.
"You jumped-up little berk! You fucking gobshite! Who the hell do you think you're talking to? You're talking out yer arse, you know that, don't you"?
