Sr Pelo is a Mexican animator and YouTuber known for loud, expressive voice acting in his animated parodies and Pelo Talks videos. His exaggerated greetings became a recognisable part of his persona, shared by fans as short reaction clips outside the original videos. Hello bois circulated on soundboards and in edits because the line works without context, functioning as both a greeting and a punchline. It remains popular with younger audiences who grew up with his animations and still use his voice to signal a silly, high energy start.

Sr Pelo says hello bois in his high pitched cartoon voice, a cheerful greeting clip creators use to open videos, streams, meme edits and group chats.
This is Sr Pelo delivering his signature greeting, stretching out hello bois in a squeaky, exaggerated cartoon voice that jumps in pitch and energy. The delivery is fast, friendly and deliberately over the top, with that familiar animated wobble that makes a simple hello feel like a character bursting through the door. It lasts just a few seconds but lands instantly, turning an ordinary introduction into a joke. Viewers recognise the voice right away, and the cheerful chaos of the line sets a playful, unserious tone before anything else has even happened on screen.
