What does “robbing the cradle” mean??
This is also known as Cradle Snatching. It refers to a situation in which an older individual seduces a much younger one. People who ‘rob the cradle’ are commonly called “cradle snatchers” or “cradle robbers”. It is not a complementary term, but it could be used in a joking fashion as did the answerer above, who referred to a husband 13 years her senior.
