Corner Moth
A corner moth is an introvert. A corner moth is an opposite of a social butterfly. As most introverts are in the corner, not really bothering anyone who passes by and try to cease interactions, and since most introverts don’t wear bright colors, they wear dull monochrome colors like a moth wings, they would refer to as a Corner Moth.
