OMG the Unidentified-Drunk-Bruises, I'm the queen of those. I got back from Mountain weekend with a fraternity and I had about 20 little pen-tap size bruises on my left lower leg on the outside. WEIRD ... I only noticed it cause the bag I was carrying kept bumping it and I was like, 'ow..ow..ow..' Then I also had about 15 OTHER bruises on my butt/thigh/leg/arm/knee , however I did spend a whole weekend in a campground with a fraternity... so I guess that's a good explanation...
