Boot skiers united. I was going down a steep enough hill boot skiing and decided if I could do a jump. Accidentally smashed a guy in the back of the head with my boot :P

When someone didn't think I would punch them in the face for being a dick, I wailed on them as hard as I could. Wasn't my proudest moment, I'm over it now but it was pretty crazy when I noticed blood on my knuckles afterwards.
