The phrase comes from Brazilian gaming slang, where tiltado means a player who has lost composure and started playing worse. Cabelo rosa simply points out the pink hair of whoever is being called out, turning a generic rage comment into a very specific joke. Clips tagged with names like Dynquedo and Luci suggest it spread through League of Legends streams and highlight edits in the Brazilian community, then onto soundboards where short Portuguese callouts are reused as instant reactions for any frustrating play, in any game.
