What does WTFO stand for?

What the f***, over


WTFO is an expression of astonishment, which you're most likely to encounter during a text or chat conversation. It means roughly the same thing as "What in the world?" or "How the heck?"

The O in WTFO stands for "over." In radio communications, ending a message with "over" tells the recipient that you're waiting for a reply. In this case, the person who sent you WTFO is likely hoping you'll explain the message that prompted them to send you this crass acronym.
