Usage
Where does the word bonkers come from? Bonkers is a funny-sounding word. It's a goofy, lighter, informal way to say "crazy" or "nuts”—but keep in mind that’s it not so fun to make fun of people’s mental health. Its origins are unclear, but bonkers is first recorded as British naval slang for "a bit drunk" in the 1940s—perhaps acting like someone has bonked, or hit, them on the head. The roots of these other words may get a rise—of laughter or surprise—out of you. Run on over to our roundup of them at "Weird Word Origins That Will Make Your Family Laugh."
