may-december

a relationship between people, with a large age gap.

When a girl/boy is in a relationship with a man/woman whom is atleast 15 years older than they are.

May/December relationship refers to a relationship between two people where one partner is in the "winter" of their life (old) and the other partner in the relationship is in the "spring" of their life (young). This can go either way such as the woman is older or the man is older. Being a nonspecific term, it encompasses the concept of slang words like cougar or lech (which is offensive if used on couples who are serious). This term is also tied to concepts such as "robbing the cradle."

May/December relationships can either be superficial or serious - so the term doesn't itself say anything about the status of the relationship.

Basically any kind of involved relationship where there is a substantial age difference between the two people and the relationship does not consist of either partner being considered legally underage (which is commonly known as pedophilia which is something else entirely).

A May-December Romance is an instance of the romantic involvement of two parties between whom there is a considerable age difference, often because one individual has an ulterior motive, such as money, status, etc.

The reasoning behind this designation is that while one person is young and in the "Spring" of his or her life (thus, "May"), the other is in "Winter" (ergo, "December").

However, there are many instances, as in the case of my own clandestine affair with the most wonderful woman in the world, where the age difference is either inconsequential or isn't even a considerable enough gap to constitute a May-December Romance.
