Short meme clips like this one tend to circulate through soundboards and fan communities rather than coming from one clearly documented scene, and Best Girl has followed that same path. Creators reuse it because the phrase is instantly understood in anime and gaming fandom, where fans constantly debate and crown their favourite female character. Its brevity makes it easy to drop into edits, reaction videos and streams without breaking the pace, which has helped it stay in rotation long after longer meme sounds fade.
