Morphology

save + someone's + ass

The verb 'save' clearly signals rescuing, so a learner who knows 'save' and 'someone' could infer a general rescuing meaning; however the noun 'ass' is a vulgar/body-part term whose use here is idiomatic/metaphorical ('butt'/'body' = person/position) and functions as a colloquial intensifier rather than literally indicating what is rescued. Because the overall sense is a predictable extension of 'save' but relies on slangy metaphor and register knowledge, it is not fully compositional for a B1 learner and should be classed as semi-transparent.

Etymology

Save someone's ass comes from a strong image: imagine someone pulling another person's ass, their back side, out of danger at the last moment. That's why it now means 'to rescue someone from a difficult or dangerous situation'.
