The 'You're So Portuguese' meme originates from a gameplay video of the indie horror game 'Voices of the Void,' uploaded by Markiplier in early 2024. During the video, Markiplier encounters a strange, alien-like entity and, with complete sincerity and confusion, exclaims, 'You're so Portuguese.' The absurdity of assigning a specific human nationality to a bizarre extraterrestrial creature immediately resonated with fans, turning the clip into a viral sensation on TikTok and Twitter. It is widely used as a reaction to something inexplicable or to jokingly label friends and objects with a completely unrelated trait, capturing the chaotic and surreal humor Markiplier is known for.
