A jester usually appeared in court back in the medieval days to entertain noble members of the court. A jester has also been referred to a person who is acting foolish or joking around in modern days. The role of the jester is to make others laugh, and a jester was even around in Egyptian days to keep the pharaoh entertained.
A jester tattoo is symbolic of having fun and joking around with others. The person who chooses a tattoo design of this type typically has a good sense of humor. On the other hand, a tattoo design of an evil jester suggests being able to triumph over life.
