Boyfriend: "How's your day baby?"
Girlfriend: "horrible, a project for this new client is a mess, no one is taking responsibility for it, we are all over the place for deadlines, that it is becoming a fucktastrophe"
FUCKtastic is like fantastic but so much better.

You can even say it when you have an orgasm, or better, a RAWRgasm :)
