live target
A person who while out in public begins to cough uncontrollably without covering their mouth and doesn't bother to wash their germ filled hands before touching random store items, shopping cart, and door handle.
" I just saw that fella over yonder spitting cooties all up in his hands and spreading them there germs everywhere."
"Is that right, somebody call the boys and tell em we gots ourselves a Live Target over here"
