Obsessive-compulsive disorder

Also known as OCD, obsessive-compulsive disorder is a neurotic mental illness in which intrusive, negative thoughts and/or impulses which regularly enter the person's mind (obsessions) are counteracted by repetitive acts or rituals performed to alleviate the anxiety and general distress created by these obsessions. It is possible to qualify for a diagnosis of OCD if only obsessions or compulsions are present, although the vast majority have both.

An anxiety disorder in which uncontrollable intrusive thoughts and mental/physical compulsions make sufferers miserable. These intrusive thoughts can include violent and taboo obsessions that make the sufferer question their identity.

It's a painful, torturous disorder I'd wish on nobody.

Is a fairly common problem where people experience ‘obsessions’, recurring unwanted thoughts which are difficult to stop, and ‘compulsions’, rituals of checking behaviour or repetitive actions which are carried out in an attempt to relieve the thoughts.

Disoder in which the sufferer has a 'need' to have everything perfected to the 't'. They are usually very anal and will induce bodily harm should you ruin their arrangements.

FOCD is the term describing someone's need to turn every bit of information written down as notes into flashcards.

To be so absolutely obsessed with a person that one talks about this person in everything that one does.

Common to many gamers, OCRD is the obsessive compulsive reloading of weapons in FPSs in order to maintain a full clip at any given time.

Generally this presents as reloading before and after every encounter in a game even if only 1 or 2 shots were fired and the clip has 60 rounds. A gamer with the disorder will experience the distracting need to reload if they know their clip isn't full, similar to an itch or a nervous tic of other OCDs.

In its worse presentations, OCRD will leave a player absent-mindedly reloading before the action has finished, perhaps after killing one or a few enemies while more are still shooting at the player. This leaves the player useless and vulnerable for upwards of 5 to 10 seconds.
