The 'Ice In My Veins' pose was popularized by NBA player D'Angelo Russell during a 2016 game after hitting a clutch shot, where he pointed to his forearm to signify his 'cold-blooded' performance. The gesture quickly transcended sports, becoming a viral sensation on TikTok and social media where users recreate the pose to celebrate moments of extreme confidence, coolness under pressure, or simply performing a mundane task with professional-level intensity. It is frequently used to highlight high-stakes situations or to flex one's achievements with a humorous, stoic flair.
