Shy Guy first appeared as a masked enemy in Super Mario Bros. 2 in 1988, originating from Doki Doki Panic, and became a recurring Nintendo character in platformers, Mario Kart and Yoshi games. Because the character wears a white mask and robe, later games gave him squeaky, muffled vocal noises instead of dialogue. Short clips of those sounds spread through gaming soundboards and meme edits, where the mee wrrr noise is now used as a shorthand for bashfulness, confusion or a cute non verbal reply.
