As well as a name given to the office creep who is so far up the boss that only their toenails are visible, the facts on caring for toenails (the ones found on your feet) include this piece of advice: When cutting one's toenails, always be sure to do so in a straight line and not a curve. By doing so you leave sufficient growth of toenail protruding beyond the toe as to avoid the unpleasant experience of ingrowing toenails, which can be very annoying and painful (see "office creep" above).
