up

adj

1.

American

'dried', having forgotten one's lines. A theatrical term of uncertain origin.

2.

exhilarated or intoxicated, high up against the wall exclamation a shout of rage, defiance or menace. This Americanism, chanted on anti-war or Black Power demonstrations in the late 1960s and early 1970s, and invariably followed by the epithet motherfucker, was intended to evoke the righteous rage of a revolutionary mob about to summarily execute their oppressors, and to parody the police instruction when 'spreading' a suspect or captive.
