I'm a guy, and one that doesn't really like Christmas flicks.
There are two exceptions. First is Bad Santa with Billy Bob Thornton. Second is possibly one of the greatest "guy movies" ever, Die Hard with Bruce Willis. It happens at a Christmas party and the good guys wind up winning. That's as close to a Christmas Movie as I'm going to watch, pretty much ever. If you haven't seen either Bad Santa or Die Hard they come highly recommended from the resident PLRGrinch.
