Kyleitis 

1) A chronic disease that occurs when a person loses all athletic ability and in turn becomes a total doofus during any sporting event. Usually cured withing a short period of time, but may linger for years in some cases.

2) The inability to play any sort of sport, it is very contagious...as a matter of fact it sucks the atheletic ability out of anyone near a person that is infected with Kyleitis

Well Bryce didn't get the golf ball past the ladies' tees on his drives, looks like he has a case of acute Kyleitis.

Kyleritis 

A long-term disease that is spread by excessive kisses and/or snuggling and hugging with your best friend. Symptoms include an over-inflated sense of self confidence in one's sexual jokes as well as perceiving oneself as hilarious when, in reality, they are just annoying. Adorably annoying.

I think I have Kyleritis because I've been telling so many 'your mom' jokes.
