a person who is clearly ill and doesn't have enough sense or concern for those around them to stay home from work and out of the general public. Also applys to someone who injures them-self and instead of cleaning the wound and covering it walks around with blood dripping as if it is a badge of honor. No one wants to come in contact with your bodily fluids!!!
Man, you are a frickin' biohazard! Go home before you get us all sick!
