No verified source exists for who first recorded the 'Cooper Johns gaayyy' clip, and with only a handful of plays it appears to be a small user-uploaded in-joke rather than a quote from a show or viral video. Its appeal comes from the classic playground-taunt format: stretch a name into a singsong jeer and it becomes instantly reusable. It belongs to the same family of elongated shout memes as clips like yoooooooooooo, and survives as a niche soundboard button for friends roasting each other by name.
