Top Definition
ANS is a serious condition discovered by doctors in 1972. Symptoms of ANS vary, from picking up twigs and leaves with your mouth to sprouting 'feathers' and sitting on said nests for weeks at a time waiting for your young to hatch, but there is no young because you are crazy. There is no cure for ANS, you have to live with this disease forever.
Currently, ANS patients are being held hostage in China and are being used to breed genetically mutated birds of war for the chinese government. Any patient found to have ANS is shipped against their will to China to continue this experiment. Some may be shipped to N.Korea to aid in nuclear testing.
