    One I use in the garage when I mess up:

    W.T.F. have I done now?

    For some reason, I typed W.T.F. without the periods and it changed to WTH when I posted.

    IIRC when we test drove a Honda HRV and was told that when you release the brake it holds the brake on momentarily wile you change pedals to prevent rolling backwards.
