Metal Sonic is the robotic rival of Sonic the Hedgehog in Sega's Sonic games, first appearing in Sonic CD in 1993 as a cold mechanical double built to match Sonic's speed. This clip pairs that villain image with modern internet slang, where a ragebaiter is someone who posts only to provoke anger. The contrast between an old game boss and current online language is why it spreads in edits and gaming posts, used whenever someone wants a dramatic, robotic way to accuse another person of stirring trouble.
