The LUL emote is one of the most iconic and widely recognized emotes on Twitch, featuring the laughing face of John "TotalBiscuit" Bain, a prominent video game commentator and critic.

The image for LUL was taken from a real photo of Bain laughing heartily during an event in 2013. Over time, it was humorously circulated and eventually transformed into an emote on Twitch.
