A snowman would be a great gift for a guy friend, especially if they're into winter activities or enjoy the outdoors. You could build a snowman together and then have a snowball fight or go sledding. You could also get creative and make a snowman-themed gift basket with items like hot cocoa mix, marshmallows, and winter-themed snacks. Alternatively, you could get him something related to his interests or hobbies, like a book or a new piece of equipment for a sport he enjoys.
