Shota Aizawa, also known as Eraser Head, is the weary homeroom teacher of Class 1-A in My Hero Academia, the long-running anime and manga series about students training to become heroes. His tired, blunt delivery has made him a favourite for reaction clips, and short moments of awkward silence or deadpan discomfort are often lifted from scenes and shared as standalone sounds. On soundboards and in fan edits, this clip is used less as a quote and more as shorthand for cringe, embarrassment and a teacher who has seen it all before.
