RNS 

Retarded Nose Syndrome. If one has a chronically runny nose from a long-lasting illness, or just unlucky enough to have abnormally runny nose genes, they are said to have RNS. Also sometimes known as Runny Nose Syndrome, for those easily offended.

Heather: Why do you have such a huge pile of nasty tissues by your desk?
Me: I have an acute case of RNS, once it starts it takes hours to die down!
Heather: Real nice.
