Cheap sonofabitch. Will argue at length why s/he shouldn't have to pay for something. Mr. Pink from Resevoir Dogs. Often has few if any other friends because of
reputation for cheapness. Frugal beyond practicality, cheap for its own sake.
The saying is in
reference to an earlier version of the US Nickel, which had a picture of a buffalo on it. The phrase is
sometimes updated as: "He'll squeeze a nickel till a booger flies out of Jefferson's nose."
