The kind of guy who is fiercely loyal, hilarious and has your back. Yeagers have the most intimidating scowl but deep down they are a big softy who loves to giggle and would do anything for you. They also have the highest calves you have ever seen. They make the best boyfriends because they will also become your best friend, and the person you well completely comfortable and safe with. Not to mention they are sexy as hell, the best kissers, and give the warmest coziest hugs. They also naturally have the BEST butt ever.
