The Planet Money folks are at it again — explaining a complicated issue with humor and easy-to-understand examples.

David tells us that among the other over-used words or acronyms the Planet Money team considered using in its hypothetical were:

— "My bad."

— "You're fired."

We thought of "lol" (laugh out loud).

Anyone have some other examples of words, acronyms or phrases they'd like to see capped? Feel free to add them in the comment thread.
