Beetle-Rash
An extremely rare skin rash you can only get from violating a dead body that appears on your face, red and in the shape of a Glasgow smile. This is only contagious via transferring sweat or fluids via sex with said individual.
This chick I worked with went to Vegas for the weekend and hooked up with this stripper and totally got beetle-rash. Turns out he worked as a mortician during the day and moonlighted as a stripper and forgot to shower that day, eek!
