The exact recording behind this clip is unattributed, which is typical of viral WhatsApp voice notes that spread through forwarded chains across Peru rather than a single published source. The phrase itself comes from Lima street slang, where 'causa' means buddy and 'flaca' is slang for a slim woman, and the exaggerated delivery turned a common catcall into a shareable joke. It circulates the way many WhatsApp voice notes do, passed between football groups and meme pages, remixed into TikTok edits, and kept alive because the slang instantly signals Peruvian humor.
