The exact origin of this clip is not documented, so it is best understood as a short WhatsApp audio that circulates among Portuguese-speaking gaming chats. Its title points to a simple idea, today is the day, paired with Dota-flavoured music, and that combination makes it easy to forward when friends are organising a session. Short mixes like this spread because they are quick to send, instantly recognisable in a chat thread, and reusable whenever a group wants a light-hearted signal that playtime has arrived.
