Pip-Squeak Pop
  
A 1970s novelty song popular around the same time as "Kung Fu Fighting." The Ramones stole the melody for "Blitzkrieg Bop."
Also, a term related to penny stocks. Penny stocks are pretty much what you might think there are. They are stocks that trade at a price so low that you can measure their worth in pennies. They don't show up on the NYSE or NASDAQ. Instead, these shares exist on the back alley exchanges of the over-the-counter market and pink sheets.
It doesn’t take much to move one of these small-time stocks by a large percentage amount. A stock trading at four cents rises to five cents. That's a 25% increase. It moved one penny, but notched a double-digit percentage advance.
A pip-squeak pop describes one of these moves. A stock with a low initial value posts a relatively small move in absolute terms (maybe just a few cents), but that price change equates to a substantial percentage gain.
