🛒내돈내산

originThe expression comes from Son Min-su, a character in the Korean webtoon Cheese in the Trap. Because the character obsessively copies Hong Seol’s style and behavior, Korean internet users began using 손민수 as a noun and 손민수하다 as a verb for copying someone’s look, taste, or items. The exact first online use is hard to pin down, but the term spread widely with the webtoon and later drama fandom.

originOOTD spread through fashion blogs and Instagram-style social media posts as a short tag for “Outfit of the Day,” especially with mirror selfies, daily looks, and style-sharing culture.
