A triumph is a well-earned victory. It'll make you pump your fist and yell "Hurrah!"
Triumph can be a noun or a verb, so you can have a triumph after the big game when you triumph over your opponents. Either way, it's a way to rejoice and a reason to whoop it up. The word comes from the Latin triumphus which is an "achievement, success, procession for a victorious general or admiral." The jury's still out on whether it comes from the Greek thriambos, as a "hymn to Dionysus," but it's fun to imagine that a triumph is a song to the Greek god of party animals. Fittingly, a Triumph is also the name of a motorcycle, a cool car, and a hard rockin' band from Canada.
