When your anniversary falls on Valentines Day. Generally men come up with this so they don't forget their anniversary and they can kill two birds with one stone.
My anniversary fell on Valentines Day. So I made up the word Valeversary so I will never forget.
a 2 in 1 holiday in which a couples anniversary falls close to valentines day so they celebrate both days together.
Our two year valeversary is feb 22 so instead of buying two seperate presents, I only have to buy one!
