Umm... yeah. Back in (cough cough) 1980, I was involved in an exhibition game in Tokyo. (OK, I was in the band, but the crowds seemed more interested in bands than in football.) We paraded all over the city for a week, as an extended advertising stunt.
Anyway, one of the sponsors, and the only beverage that they supplied us with, was some stuff called "Pocari Sweat." Served warm. Kind of... ewwww.
There was much discussion of exactly what kind of animal a "pocari" might be, and much hope that it wasn't something too disgusting.
