Josh Zerka, known online as Zerkaa, is a member of the Sidemen, the British YouTube group formed in 2013 alongside creators such as KSI and Miniminter. Short voice clips from their gaming sessions, challenges and podcasts are frequently isolated by fans and reshared as reaction sounds. This numbered upload reflects that fan editing culture rather than an official release. The clip stays in use because Sidemen references are instantly understood by a large online audience, making even a one second snippet useful for jokes, edits and group chats.
