The HeyGuys emote features Selnay, a former Twitch employee, waving with a cheerful smile. It was introduced as a global emote on Twitch and quickly became the universal way for viewers and streamers to greet one another. Beyond its use in live chat, the image has evolved into a popular meme template used to signify a friendly entrance, a sarcastic 'hello' in awkward situations, or a simple acknowledgement of a community's presence. Its longevity stems from its wholesome nature and the widespread recognition of Twitch culture, making it a staple for anyone looking to make a welcoming impression online.
