Shaking your booty vs. Drawing on a booty

So I'm on call as we speak with my friend Marcie and we're just admitting a girl with some butt abscesses (i.e. pockets of infection on her butt). She's actually doing pretty well, just needs some IV antibiotics and then will go home. However Marcie and I were just lamenting that fact that instead of going out dancing on a Saturday night and shaking our booties that instead we're stuck in the hospital and are having to draw on a girl's butt or booty (Mom, that means butt) to document the spread of the infection. Sigh ...
