1. An excessive fear of disorder, disarray, disarrangement, or of being in an untidy situation: "Some ataxiophobiacs have obsessive-compulsive disorders that are persistent, intense, senseless, and worrisome; in fact, they tend to be so excessive at keeping things in order that they make it nearly impossible to exist with others who are of a less-than-orderly nature."
2. An abnormal fear of falling or tripping: "Ataxia is a lack of co-ordination in the muscles which is a symptom of damage to part of the central nervous system and so people who have ataxiophobias may be that way because of their experiences in swaying or even falling down; especially, if they close their eyes even for a second."
