The phrase comes from Brazilian television advertising for Hyundai, where do mundo works as a big, boastful claim attached to the brand name. Short slogan clips like this spread easily on soundboards and in chat groups because they are instantly recognisable, easy to quote and funny without any visual context. Brazilian meme culture often reuses confident commercial lines out of context, and this one survives because the delivery sounds far more epic than the moment it is normally pasted onto in edits, reactions and jokes among friends.
