Cousins hold a special place in our lives. They're the built-in best friends of our childhood, the partners-in-crime at boring family functions, and the people who understand our crazy relatives like no one else can. Whether he was your first-ever roommate during summer vacation or the cool older cousin you always looked up to, his birthday is the perfect chance to celebrate that unique bond.
Finding the right words can be tricky. You want something that's more personal than a generic "Happy Birthday," but that perfectly captures your specific relationship. Don't worry, we've got you covered. From hilarious roasts to heartfelt tributes, here is the ultimate list of happy birthday wishes for your male cousin, designed for every type of bond.
