I couldnt stop laughing

I just had a game in which i just couldnt stop laughing.So i was playing Sona support and my friend jungle and our mid and adc were speaking in a different language(the adc was jhin).The midlaner told to his friend something in that languange and ghostblade.I really was not paying attention to his items until a fight where he was dealing no damage and we started to run just to see that he 2 ghosts went out of jhin into the enemies only to realise that he had built frost queens claim.I started laughing histerically because instead of ghostblade he somehow bought frost queens claim.Btw i am gold 2 and my friend is gold 5, yet this dude needed his friend to tell him the build, and he doesnt even know the items in a gold level game.I dont expect to play with pro players but still this was really funny.And if you ask, no he was a very weak player both macro and micro probably just borrowed a friend's account without even being lvl 30 on his main account just to play ranked with his friend
