Meaning: If someone tells you that you're off your trolley, it means you have gone raving bonkers, crazy, mad!
Etymology: Originally the phrase was specifically about what we'd now call "mood swings." Now it means "to be crazy," but it used to connote a "normal" person who periodically, and unexpectedly, goes crazy. The British latter adapted this phrase to "off your trolley".
