Did you know?

For those who don’t give a hang about a bad reputation, being notorious for unpopular behavior is no biggie. (Being notorious for topping the Billboard charts? Now that's a Biggie.) Although notorious (which comes from Latin noscere, "to come to know") can be a synonym of famous, it's more often a synonym of infamous, having long ago developed the additional implication of someone or something disreputable. The Book of Common Prayer of 1549 includes one of the first known uses of the unfavorable meaning in print, referring to "notorious synners." You know what they say: more notorious synners, more problems.
