Bottom Fishing
  
Google this term and go to like the fourth or fifth page, and things get a little weird. Uh...maybe don't Google this term.
The literal definition of "bottom fishing" has to do with...actual fish. Like...getting those fish that live at the bottom of lake. Kinda like getting the last chip in a can of Pringles.
In finance, the term involves investing in something that has...fallen on hard times. Putting money into a stock that has recently dropped dramatically. Buying a haunted house. Picking up a car at a police drug-bust auction.
By aiming low in this way, an investor can pick up some bargains. The market might have overreacted, and that stock is due for a rebound. An exorcism and a coat of paint and that house is a great flipping opportunity. The sound system in that former drug car is really boss. And so on.
