#15: Booyah!
There’s something so satisfying about shouting “Booyah!” in a moment of triumph. Even if this word is not “cool” anymore, it’s still so fitting for that unique feeling. Booyah isn’t just a word. It’s a way of life. It’s an exclamation that encompasses so many complex human emotions in just two syllables.

Okay, we’ll stop waxing poetic about the word booyah. We never thought that would actually happen. As with many of our mainstream slang words, the term booyah started off in the Los Angeles hip-hop scene. It took off in the mainstream until sportscaster Stuart Scott began saying it during his live sports commentary.
