Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means leap so the verb vocab version means to leap. It also means to jump or to bounce.
You go to leap and leap again. You do it so much that you start sweating, which is causing a foul odor (おど) to come from your body.
