The phrase comes from Spanish slang where laburar means to work, especially common in Argentina and Uruguay, and manga means a bunch of people when used as an insult. Coquemones is a twisted pronunciation of pokemones, turning the insult into nonsense that sounds funnier the louder it is shouted. The clip spread as a shareable voice note on soundboards and in group chats, where short angry rants are reused as reactions. It stays popular because the wording is specific, rhythmic and instantly understood by Spanish speaking audiences online.
