one-up

heard an older woman complain about her aches. But her friend one-upped her: "I woke up this morning and thought I was dead because nothing hurt."
上の文はRDの８月号にあったLife, It's really like that あったもので、文中の "one-upped" は初めて見る動詞で意味も大体想像が付く単語ですが、面白い表現なのでメモしました。　一応辞書で意味を確認します。
Dictionary.com: to get the better of; succeed in being a point, move, step, etc., ahead of (someone): They one-upped the competition.
Encarta: gain advantage over somebody: to gain an advantage over a rival or opponent ( informal ): Looks like I've been one-upped again.
American Herritage Dictionaryの説明を読むと "one up" 名詞用法が先にあったようです。
Having an advantage or lead over someone, as in Sara is one up on Jane because she passed algebra in summer school. This expression comes from sports, where it means to be one point ahead of one's opponents. It was transferred to more general use about 1920.
日本語の一枚上手を連想させる表現ですね。
