🏆 sugoi = so-GOOD-oy! — the shout when something is terrific
Sugoi sounds a bit like so good-oy, which matches its everyday meaning: terrific, great. Etymology twist: 凄い originally meant dreadful or chilling, then flipped to amazing — the same path English took with terrific, from terror to praise.
