The phrase comes from the Minecraft community, where a young server owner asked how much dedotated wam should be added to a server, meaning dedicated RAM. The misspelling turned a normal help request into a copypasta that players quoted, reposted and read aloud in silly voices. It became shorthand in gaming chats for clueless tech questions and overconfident server advice. The joke survives because the mistake is instantly understandable to anyone who has hosted a game server or dealt with lag.
