The 'Sup Son' meme originated from the StarCraft II professional gaming scene, specifically associated with the Terran player SeleCT (Kyung Hyun Kim). During a victory celebration, SeleCT performed a confident shrug that became his signature move, later immortalized in text as the shrugging emoticon ¯\_(ツ)_/¯. The phrase 'Sup Son' became a rallying cry for his fans and a classic way to taunt opponents after a decisive win. Over the years, it has transcended the StarCraft community to represent general nonchalance, victory, or a cheeky response to any situation where a player feels superior or unbothered by a challenge.
