How do I create a wedding hashtag? Is it something I go online and "make official" or I just start hashtagging my stuff with the same hashtag? Lol please help

I'm looking for songs for my son and I to dance to at my wedding. He'll be about 1 1/2 by then and almost everything I've found feels like groom and mother dance and it all sounds like "goodbye". I don't mind something more upbeat. Any suggestions ?
