I noticed that the demi-official USA national (soccer) team supporter's group has a name for the folks who lead their section of the stands in chants/cheers; a word I'd never seen used for that before: "Capo".
I'm curious if this is just something they came up with on their own, or is this an actual common use for this word?
The proper English word for this role probably really ought to be "Cheerleader". However, while that's probably what cheerleaders did in the 1920's, these days cheerleaders are essentially glorified dance/gymnastic troupes. So I suppose I can see where a new word for the actual act of leading the fans in cheers would be required. Is this that word, or just American Outlaws' attempt at it?
