What is what does being a valentine mean?

Being a valentine generally means that you are someone's romantic partner or love interest on Valentine's Day. It can also mean that you have agreed to exchange cards, gifts, or tokens of affection on the holiday. The tradition of Valentine's Day goes back to ancient Rome, where a festival called Lupercalia was held in mid-February to celebrate fertility and the coming of spring. Over time, the holiday became associated with romantic love, and it is now celebrated around the world as a day to express love and affection for those closest to you.
