Fortnite is an online game developed by Epic Games, known for its battle royale mode and large library of cosmetic emotes that players use to dance and react in matches. Dance emotes became a major part of Fortnite culture, spreading to TikTok, YouTube Shorts and Discord as short meme clips detached from gameplay. The sigma dance version taps into the wider sigma meme, where acting cool, independent and unbothered is played for comedy. That mix of a recognisable game emote and a popular internet attitude keeps the sound in circulation for edits and reaction videos.
