The expression usually implies that others are suffering the censure or opprobrium properly due the “innocent” one who “smells like a rose.” Despite the phrase’s implied vulgar origins, it is now commonly considered inoffensive and frequently appears in a variety of informal contexts.

get off scot-free To escape deserved punishment; to be excused from paying the appropriate fine or penalty; to be released without castigation or just punishment. This expression originated from scot and lot tax allotment,’ which was formerly levied on all English subjects according to their ability to pay.
