Whup has long been a variant of whip, and the Oxford English Dictionary has examples of its use from as long ago as the 16th century (though the word was never widespread until the late 19th century). In modern usage, it’s a mainly American colloquialism meaning to defeat overwhelmingly. Your spell check might disapprove of it (ours does, at least), but it’s a perfectly good word.
A whoop is a cry of exultation, a war cry, the whooping cry of a bird, or a harsh coughing sound. The word also works as a verb for to make a whooping sound. Some pronounce the word with an h sound and some with a w sound.
Whoop is conventionally used in the sarcastically celebratory interjection whoop-de-doo, as well as in the equally sarcastic expression big whoop, which means the same as the sarcastic big deal. It’s also used in whoop it up, meaning to have a joyous celebration.
