With no confirmed source work, artist or original recording attached to the name, Trey Woo circulates mainly as a short soundboard clip shared under its simple title. Its appeal comes from how recognisable a single woo shout is, even without context, and how easily it can be dropped into unrelated videos. Online, short vocal reactions like this spread because they are easy to remember, quick to trigger during livestreams, and flexible enough for celebrations, jokes and ironic hype. That brevity keeps it useful as a reusable reaction rather than a full song or dialogue clip.
