(n.) A disease of one's patience that is spread via contact much like the STD herpes onto one's patience levels so that whenever one encounters a great deal of stress the infected person 'flares up' and causes a flood of liquid to come pouring out, usually in the form of saliva, as a result of that person becoming annoyed the fuck out. Highly contangious if not properly treated and prevented. Various forms of treatment include: anger management counseling and the use of a condom.
