Tamo junto is a widely used Brazilian Portuguese expression shortened from estamos juntos, meaning we are together in the sense of loyalty and support. Online, short voice notes using the phrase became a reusable reaction for thanking someone, agreeing with them or closing a favour between friends. Adding the name Marcos makes this version personal and specific, so it is shared mainly when the joke or reply is aimed at a Marcos, or when that direct address is part of the humour in chats and memes.
