Anything that's obsessive-compulsive relates to a kind of anxiety characterized by a combination of obsessive thoughts and repetitive behaviors that help relieve the anxiety these thoughts cause.

Obsessive-compulsive disorder (OCD) is a mental disorder that causes people to think or worry obsessively, and to become so anxious that they feel a need (or compulsion) to perform some kind of ritual. These obsessive-compulsive actions can include counting, tapping things, moving or jerking their bodies, turning lights on and off, and nail biting. The term obsessive-compulsive dates from the 1920s, combining Latin roots obsessus, "besiege," and compulsus, "forced."
