Origin obscure: perhaps originally a reduplication or rhyming expansion of rory, roary, from roar (n.) or (vb.)
The English Dialect Dictionary cites it from South Lancashire as meaning ‘a state of hurry or excitement’. After 1680 it was sometimes abusively associated with Tory (n.); but there can hardly have been any original connection. Reference to the Irish Tories or outlaws and marauders is chronologically possible, but not evidenced.
