What is a may December romance?

A May-December romance is a relationship between two people with a significant age difference, typically with the older person being the male partner and the younger person being the female partner. The term is derived from the months of May and December, which represent the beginning and end of the year, respectively, and thus symbolize the wide age gap between the partners. May-December romances have often been the subject of discussion and debate, with some people finding them controversial while others view them as simply a matter of personal choice.
