@MaaswReturns I was making reference to the Super Smash Bros. Ultimate presentation that outlined Terry Bogard. In it, after listing out the SNK character cameos on the King of Fighters Stadium stage, Masahiro Sakurai pointed out that they had to exclude the popular Mai Shiranui because her cleverage would cross-contaminate with the game's A (All Ages) rating from the CERO (the Japanese ESRB).
This was localized more humorously as, "Super Smash Bros. Ultimate is for good boys & girls of many different ages", to the point where it became a small meme.
