An interrogative as to the events that have come to play, be it in the distant past, the recent past, or the present. This phrase may or may not use a question mark, but is an interrogative, regardless.

This phrase, popular among geeks, alludes to the poorly-translated Sega game Zero Wing; however, it is not always used for its pop culture value alone.

Literally: "what happened?" Comes from some Japanese video game in a poor English translation. See also: all your base are belong to us, someone set up us the bomb, make your time, et al.
