Cranial Rectimitus 

The serious medical condition where the sufferer is known to have their head lodged firmly and permanently up their own ass. Symptoms are readily apparent in the patient's behavior and verbal interactions.

Ross' behavior was nigh on inexplicable... the only possible explantion for his asinine behavior was a terminal case of Cranial Rectimitus.

REPTILITIS 

A disease that manifests itself with the same symptoms as the common cold but is really a virus spread by contact with snakes and lizards.

Your co-worker who owns a ridiculous number of snakes and lizards and is always coughing and sneezing has reptilis.

REPTILITIS 

What you suffer from after making out with someone who is afflicted with this reptile virus

Enjoying a heavy make out session when you suddenly feel like you are making out with an alligator because they are eating your face alive and their body gestures are that of an alligator during a feeding frenzy

Andy: Shut up, fag.
