Very common-that is what the Super Greeters call them,one of the Brazil Tour Companies even has "FIFTEENS" emblazoned on the Backpacks.Oh, I think we're all pretty familiar with large Brazilian and Argentine youth tour groups in Orlando theme parks, but I confess that I didn't initially realize that anyone called them "The Fifteens."
I'm more used to them just being referred to as the Brazilian (or South American) tour groups.
