carny fingernails
While working a manual labor job, you end up having a copious amount of dirt and foreign particles caked under your finger nails. Making you appear unclean and lecherous. Can also be in conjunction with "carny arms."
While making pizza all day, I ended up having some gross carny fingernails from grabbing cheese and pepperoni with my hands.
Ewww! You have the most disgusting carny fingernails I've ever seen! Do you ever wash?"
