An innuendo is a hint, insinuation or intimation about a person or thing, especially of a denigrating or derogatory nature. It can also be a remark or question, typically disparaging (also called insinuation), that works obliquely by allusion. In the latter sense, the intention is often to insult or accuse someone in such a way that one's words, taken literally, are innocent.
According to the Advanced Oxford Learner's Dictionary, an innuendo is "an indirect remark about somebody or something, usually suggesting something bad, mean or rude", such as: "innuendos about her private life" or "The song is full of sexual innuendo".
