Every first Tuesday of the month is the official WTF Day.

Because sometimes you just have to say it, so why not make a day of it.

resolution of craziness that happens on a particular day, taking into account what has happened and deciding that she does not care anymore, summing up what has gone completely wrong and then feeling who cares? a day of {reckoning} then discarding the pain,
When she {figured} it all out in her head... she called it

WTF day. After thinking about everything that was insane, she decided it was WTF day. If you have a rotten job and are fired, then you can call it {WTF} Day or What The Fuck Day !
