I didn't receive any requests this week, but fortunately, I was able to reverse-engineer an episode from a discussion at work earlier this week. This week's pimped word(s): beauty and beautiful. An article in the paper used the word pulchritudinous, so we looked it up. Pulchritude means "Great physical beauty and appeal," according to the American Heritage Dictionary, and pulchritudinous means "Characterized by or having great physical beauty and appeal."
However, like some of the cars that come out of Pimp My Ride, this isn't really better than the simpler word. Telling your wife she is beautiful might get you a smile; telling her she is pulchritudinous might get you a confused look at best, or slapped at worst.
Pulchritude comes from the "Middle English pulcritude, from Latin pulchritūdō, from pulcher, pulchr-, meaning beautiful."
