What's with people challenging enemies for a 1v2 room 😂

This OBITO guy lost his senses when I finished him with pan in WOW mode...he lost the match and he immediately invited me and my random teammate to a 1v2 room 😂😂 (he didn't even discussed, he had the room ready and he just sent us an invitation).......

And yeah he lost again, my random teammate kept on abusing him and making fun of him 😂😂
