The 'My Heart Is Cold' meme centers around the catchy, rhythmic lyrics 'My heart is cold, my moves are bold,' which became a viral sensation across TikTok and YouTube. Usually associated with 'Sigma' culture, the meme features characters or real-life individuals exhibiting extreme confidence, stoicism, or 'cold' behavior in the face of adversity. While it started as a genuine expression of being unbothered, it quickly evolved into a satirical trope often paired with characters like Morshu from the Zelda CD-i games or the GigaChad aesthetic. It is widely used to highlight moments of social dominance, ironic detachment, or simply to accompany a particularly smooth or unexpected action.
