Purposefully banning someone else's champion

I understand that this happens a lot, especially if say someone's playing a champion that's highly meta but they're last pick. I'm a mordekaiser player, and I duo adc bot lane with a friend of mine. We ran into the same jungler after a single bad game and he banned my champion. Is there any repercussions for this? It was obvious that he was holding onto hateful thoughts (he purposefully chose twitch jungle last game simply because he believed that we needed an adc) Many thanks!
