1. It's grammatically incorrect

The first (and the least serious) problem with claiming to have OCD because your DVDs are alphabetically organized is that you are most likely phrasing it wrong. Think about it. Saying, "Wow, Jessica, you're so OCD about your spice rack," really means "Wow, Jessica, you're so Obsessive Compulsive Disorder about your spice rack." Pro Tip: if you're actually concerned about a friend, address their obsessive compulsive tendencies rather than attempt to insinuate that they have a disorder.

2. It makes people with OCD feel crazy

Every time a person who actually suffers from Obsessive Compulsive Disorder hears someone call themselves or someone else "a bit OCD" because of a trivial reason like washing their hands twice after using the restroom, it makes us second guess our experience as a person with OCD. Even though we know that we have a disorder (maybe we've been to therapy and maybe we're even on medication), when someone you know and possibly trust plays off OCD as an endearing quirk, we think: "Is my mental illness valid, or am I just a big baby?"

3. It minimizes the severity of OCD

OCD is a serious and sometimes deadly disorder. The depression and hopelessness that often accompanies OCD means that obsessive compulsive people are at a high risk for suicide. OCD regularly prevents people from maintaining jobs, developing close personal relationships, and even leaving the house. OCD is NOT an eccentric need for symmetry or a penchant for color-coded organization. It is a disease that can ruin a person's life if not properly treated.

4. It minimizes the severity of mental illness

Along the same vein as point three, turning OCD into a flippant remark about your friend's comic book collection makes mental illness into a joke. This culture is rife with people that romanticize depression, sexualize eating disorders, and poke fun at people with social anxiety (I'm looking at you, "Big Bang Theory"). We don't need any more people contributing to the trivialization of mental illness. The notion that "everyone is a little particular about something" may be true, but it is in no way connected to the struggle of those who suffer from OCD, and it certainly isn't a joke.

5. It disrespects the struggle of people with OCD

Again, OCD is a battle. It is fought every day and there are casualties like money, time, and relationships. Until you have been diagnosed, you don't have the right to claim that you have Obsessive Compulsive Disorder. OCD isn't cute or helpful (even if is manifests itself in a desire to clean or straighten). It is a disease. You wouldn't claim to have "a bit of anemia" because you cut yourself shaving.
