What is uwu sound?

The uwu sound is a cute, high-pitched exclamation that is often used in anime and manga. It originated in Japan and has since spread to other parts of the world, particularly among online communities. The sound is typically made by pronouncing the letters "u" and "w" in quick succession, with emphasis placed on the "w". It is often used to express feelings of love, happiness, or excitement, and is associated with cute, kawaii culture. The uwu sound has also been adopted by some members of the LGBTQ+ community as a form of expression and solidarity.
