The phrase plays on informal Argentine Spanish, shortening hagamos and tomemos into hagamo and tomemo for comic effect. It is tied in its existing description to Caligaris, a name associated with festive Argentine music, and pairs two local rituals: the asado barbecue and fernet, usually mixed with cola. Short clips like this spread easily through WhatsApp groups and soundboards because the whole invitation fits in seconds. It stays popular as a shorthand for celebration, especially before weekends, holidays and football gatherings with friends and family.
