The phrase behind the clip comes from Filipino slang, where bongga describes something showy, fabulous or over the top, and day is used as a friendly form of address. It spread through short-form video, especially TikTok, where Filipino creators used it to hype friends, outfits and transformations with humour and affection. Because it is short, expressive and easy to quote, it travelled beyond its original audience as a lighthearted compliment, and it remains useful whenever a creator wants a quick, culturally recognisable burst of praise.
