Aram "bots?"

So,last night me and 3 of my buddies went into an Aram game,and what we think are bots,started cursing at us,but in really long and gramatically correct sentences wich ended with our name without the caps we had,they were playing and writing at the same time,it seemed funny for us 'cause we thought riot did a little prank on aram until in the end-game lobby,I added one,i sent "him" a message,but didn't reply all i saw it was that it went into a Queue then into champ select,we still didn't know what that was and thought about asking at boards
