Charlie White Jr. began posting as penguinz0 on YouTube in 2007 and later became hugely popular on Twitch and YouTube as MoistCr1TiKaL for dry commentary on games, internet drama and bizarre videos. His excited catchphrase, often clipped as woo yeah baby, spread far beyond his own streams through Twitch clips, TikTok edits and meme compilations. Because his fanbase quotes it whenever something long promised finally happens, the short clip now works as a standalone reaction, understood even by viewers who have never watched a full stream or video from him.
