天花板

Meaning

"Guabang" (瓜榜/Melon Chart) refers to the charts on Korean online music site MelOn. Since "melon" means 瓜 (melon) in Chinese, K-pop fans shortened it to "瓜榜." Note: Korean music shows like KBS Music Bank and SBS Inkigayo use MelOn streaming rankings as reference or major factors. Fans repeatedly stream songs on MelOn to help their idols win "#1." This is called "刷瓜" (washing melons) or "切瓜" (cutting melons).
