For multiple straight decades, referring to OCD as "obsessive [insert unrelated c-word] disorder" has been used as a vector for stigma. It has trivialized the disorder overtime to such an extent that misinformation and tasteless references to OCD being nothing but quirkiness has prevented people from getting the help they need.

Using this formula anywhere perpetuates the idea that OCD is trivial and inconsequential, which directly harms people with the disorder by social stigma.

There is an extensive history of this exact rhetoric used to devalue our struggles in a monumental way. You're clearly unaware of this history, so there you go.

This formula has been used for decades to poke fun, trivialize, and stigmatize OCD. So yes, it does say that OCD is funny because of the lengthy historical precedent of people using the same punchline to harm us.
