Center of Attention Syndrome

Someone suffering from COAS is so pre-occupied with themselves and their issues that they have a hard time paying attention to anyone else. An extreme version of being self-centered narcissists, sufferers of COAS frequently don't know that they suffer from COAS, but they would love the idea that they suffered from an illness.

Yo! That girl totally suffers from COAS, Center of Attention Syndrome. She had no idea that my dog died because she was too focused on the drama with that bitch from her job. self-centered narcissist self-absorbed douchebag
