Glitter. Tinsel. Drunk confessions at office parties. Christmas isn't exactly subtle, is it? Our Men's Grey Humping Reindeer ugly Christmas sweater shows us exactly what Santa's helpers get up to after dark. We'll give you a hint - it ain't delivering presents. These randy reindeer are making their own baby Jesus and they don't care who's watching. Still, it's got a lovely Fair Isle pattern, so your buddies won't notice straight away. Want to lose some friends? Wear at family parties for maximum effect.
