Specifically having to do with the seemingly caterpillaresque collections of facial hair that reside atop one's whites which contain an iris which contain a pupil, which all is inside a socket, which is most commonly part of a face, which also contains some sort of food inhaling mechanism and/or nasal instrument used for sniffing people you want to get to know better, and expelling mucus and other matter.
