Please help me prank my bf

I saw on tiktok that people who have played Elden Ring, get very serious about it(completely understandable) anyway I have never played and don’t really have any interest in playing it but whenever I bring up the game to my boyfriend he gets SUPER serious. (he plays it)

I thought it would be funny if I just randomly started dropping random lines from the game into casual conversations. What are some lines that he would recognize if i said??
