Dr Robotnik, also known as Dr Eggman, has been Sonic the Hedgehog's main villain since the Sega games began in 1991, always trying to slow down or capture the blue hedgehog. Lines where he confronts Sonic directly became popular as short reaction sounds online because the rivalry is so familiar, even to people who have never played the games. This particular catchphrase style fits chase memes and gaming edits, which is why it keeps being reused for moments when someone is stopped just as they think they have escaped.
