During rough sex, a girl rapes your skin with her nails, razor sharp like a Koala, with or without you noticing. She may or may not have permission to scratch the hell out you, but will do it regardless. She may break skin, but not so much to cause fatal bleeding. The victim should take a trophy shot within 30 minutes of the last scratch or immediately after taking a hot shower, which will bring out the visual definition of wounds. One should never allow their lower arms, neck, face or any other area of their body to be Koala'ed which may be seen on a daily basis by close friends, family, or employer/employees as these people might judge you.
Guy 1: Bro... This chick is a hell of a scratcher.
Guy 2: What do you mean man?
Guy 1: You should see my chest and shoulders, It looks like I got into a fight with a Koala and lost.
Guy 2: You should probably bathe in Neosporin. FML that looks like it hurts.
Guy 1: I've been Koala'ed bro...
