What's up with that
Did you see our company's stock price has dropped five days in a row? WUWT?
|DUUT||Do you understand that?|
|IDU||I don't understand|
|YTF||Why the f***|
|BAIC||Boy am I confused|
In other words, "I don't get that." Can be used as a rhetorical question or as a response to a statement.
