LUL is one of the most recognizable emotes on Twitch, featuring the face of the late gaming critic John 'TotalBiscuit' Bain laughing hysterically. The image originated from a photograph taken at MLG Anaheim 2013 and was initially introduced to the platform via the BetterTTV extension before becoming an official global emote. It is primarily used to signify genuine amusement or to mock a streamer's blunder. Over the years, the LUL emote has inspired numerous variations like LULW and OMEGALUL, remaining a cornerstone of internet gaming culture and a tribute to one of the industry's most influential figures.
