The phrase não sabe perder is common Brazilian Portuguese slang for a sore loser, and kkkkkk is how laughter is written in Brazilian internet culture. This clip spread as a short soundboard and social video reaction, shared in gaming chats and group messages whenever someone refuses to accept a result. Its appeal comes from that rematch setup described in its original description: asking to play again only to lose a second time. That double failure gives the sound a clear, reusable punchline that needs no extra context.
