on a/the rampage

on a/the rampage

Violently excited; furious. This term appears to have come from the Old Scots verb to ramp, meaning “to storm and rage.” The current cliché was known in the mid-nineteenth century. Dickens used it in Great Expectations (1861), in which Joe Gargery tells the hero, “On the Rampage, Pip, and Off the Rampage, Pip; such is Life!”See also: on, rampage
