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.

style of drum and bass characterized by aggresive sounding basslines with plenty of LFO which gives them a wobbly sound. Tempos are usually faster than other styles of dnb. sometimes reggae/ragga samples are used to add more badman flava.

jump up is sometimes looked down upon by listeners of other styles of drum and bass, as being simple music for simple brained chavs. i suggest these people go to a jump up night, get spannered and stop acting like cunts, u don't have to be a chav/rudeboi to enjoy this music! it may not be as complicated as other sub-genres but it gets people dancing!!!!
i love jump up, but i also like other styles of dnb.
