Morphology

roller + coaster

The figurative sense 'a situation of sudden or extreme changes' relies on the image of the amusement-park ride and is not transparently built from 'roller' (a cylinder) + 'coaster' (unclear or unrelated to the metaphor). Because the constituents do not compose predictably into the intended meaning and many languages use different terms for the ride, a B1 learner who only knows the parts would likely not infer the MWE's meaning.

Etymology

Roller coaster is used for a situation with sudden changes because the real ride has quick highs and lows. That's why people call a job, relationship, or market a 'roller coaster' when it goes through fast ups and downs.
