innuendo

n. hint, intimation, indirect suggestion (usually derogatory)

A sexual innuendo is a remark or question, typically disparaging, that works obliquely by allusion. The intention is often to insult or accuse someone in such a way that one's words, taken literally, are innocent. Innuendo can make use of, but is by no means restricted to, double entendre (note that doubles entendres can be unintentional, while innuendo is always intentional).
