When my big sister was a junior high school cheerleader, I would hear her practice a cheer that said:
Send them to their doom-doom-doom-doom-doom-doom!
Boob-boom-boom-boom-boom-boom!
I was unfamiliar with the word "doom" at the time, so the nearest word I could hear was "dune". I really wondered why the cheer was calling for sending someone to a sand dune.
