Manco comes from everyday Spanish, where it literally describes someone missing a hand and figuratively means clumsy or hopeless with their hands. In Spanish speaking gaming communities the word became a common insult for a player who aims badly, fumbles controls or loses an easy fight, similar to calling someone a noob. Short clips repeating the word spread through streams, voice chats and meme edits, where it is now used less as a harsh insult and more as a familiar, teasing label for any embarrassing mistake during a match.
