It occurred to me the other day that I don't remember ever hearing the term "s-tier" (meaning the best in a tier list, far better than anyone else - the highest tier) before Super Smash Bros Brawl, when it was needed to separate Metaknight from the rest of the cast.
This may be a question for English Language stack exchange, too, but I thought I would start here. What is the earliest recorded use of the term "s-tier"?
