The phrase comes from BT0, a Brazilian creator known in the Counter Strike community, where clips from his streams are widely reused as soundboard reactions. Pega o Guanabara e vem refers to Expresso Guanabara, a well known intercity bus service in Brazil, so the line is a local way of telling someone to travel over and settle it in person. It spread through Brazilian gaming chats, WhatsApp groups and meme edits because the wording is instantly recognisable to local players and sounds funny even out of context.
