The phrase comes from Brazilian Portuguese slang where calling something the new wave of the summer means it is the latest fad everyone will copy. Short voice clips like this spread through WhatsApp groups, TikTok edits and meme soundboards because the line is instantly understandable even without context. Creators reuse it ironically for cheap, silly or unexpected items, which keeps the joke fresh each season. Its popularity rests on timing and exaggeration rather than a single known source, so it resurfaces whenever a new summer trend appears.
