다 빠지다

went up and then dropped

Pairs a rise with 빠지다, which is coming down or dropping out: 올랐다 빠진 'went up and then fell', 오르다 빠지는 거 아니야? 'isn't it going to rise and then slide?'. Most lines are about prices, but the same shape covers weight — 쪘다 빠졌다 쪘다 빠졌다, gaining and losing over and over. 빠지다 on its own also means falling into something, which is the sense in 그러다 빠지세요.
