look up any word, like blumpkin:
The movement and actions of an individual with polyuria in a crowd, who must leave to urinate. This frequently involves dodging, darting, and abrupt movements towards the bathroom. "Langerhans" is from the Isle of Langerhans, an organ in the body afflicted by diabetics, who, by virtue of their affliction, urinate frequently, but the definition is not restricted to diabetics.
"After that seventh beer, John was doing the Langerhans Polka the rest of the night."
