Are you really "Fam" or do really not even like that person because they tweeted a link to the last pair in your size before you could get online and order your pair? Unless you're really fam, as in blood related or really good friends in real life, chill. There is one exception. If you can collaborate with your own sneaker company and make cardboard cutouts of yourself to give high-fives to, then you can do whatever you want and be considered a sneakerhead. Hell, you can even refer to yourself as fam. Word to Warren Buffett.
