The clip is linked to Filip Chajzer, a well known Polish television presenter, and takes its hook from everyday Polish slang where mordo is a casual way to address a close friend. Słusznie works here as a blunt rightly or exactly, so the whole line functions as a compact agreement. Short Polish voice lines like this spread through group chats, meme pages and soundboards because they are easy to drop into conversation without context, and this one keeps being reused for its laid back, confident delivery rather than any longer scene.
