썰

A juicy story or personal anecdote worth telling — usually dramatic, embarrassing, or unbelievable. From 설 (說, story/tale), evolved into 썰 in internet slang. When someone says "썰푼다" (I'm dropping a 썰), you know something worth hearing is coming.

썰 = story, tale (evolved from '설' 說, meaning story/tale)
