Word to the Wise: Bugbear

A "bugbear" (BUG-bare) is a persistent problem or source of annoyance.

Example (as used by David Cross today): "Or how about another bugbear of mine: Only after you’ve completed a website’s form does it tell you that your phone number should be formatted in a certain way or that your password ‘must contain a minimum of eight letters and numbers, one of which must be a capital letter.’"
