Terio first went viral on Vine in the early 2010s, when short clips of the young dancer performing to cheers of 'ooh kill em' were shared and remixed across the platform. The phrase became his catchphrase and quickly moved to Instagram, YouTube and sports celebrations, with athletes and fans copying the shout for big plays. Even after Vine shut down, the audio survived through reuploads, compilations and soundboards, and its hype-man delivery still signals an overconfident entrance or dance moment online.
