Ever wonder why we refer to someone up to no good as a “hooligan”?
It’s a fairly recent word, having originated circa 1850. In London at that time the Irish surnames O’Houligan and O’Houlihan were very common. It was not uncommon to see newspaper reports of petty crimes were the person apprehended carried one of these two surnames. The short form of the name became generic slang for a criminal.
