The term describes people from the north aka YANKS, YANKEES, or GREASE-BALLS, rapidly populatiing the south while having very unpleasant body odor and smell. (mainly fishy or just bad smelling)

In recent years, people have seen the effects of YANK STANK FEVER in the south ex; colleges and college towns.
The party last night would have been much better, but YANK STANK FEVER caused everyone to leave cause of their yank like ways and very bad smell.
