Murat Övüç is a Turkish social media personality famous for flamboyant, theatrical videos full of dramatic one-liners and exaggerated reactions. His confrontational style made him a staple of Turkish meme culture, where short clips of his outbursts circulate widely across social media. 'Bu lavuk kim' — roughly 'who is this dude' — became one of his most quoted dismissals, used online to brush off or ridicule someone. Its exact original video is unclear, but the line thrives as a reaction meme in Turkish edits, gossip pages and comedy compilations.
