loco
Off one's rocker
Loco is Spanish for crazy, borrowed into English slang with the same meaning: He went loco and started smashing furniture.
The word appears in phrases like en lo loco and compounds like locoweed—a plant that causes erratic behavior in livestock that eat it.
In railroading, loco is informal shorthand for locomotive.
