Well, the rest of the song helps, in that it specifies that (1) the toast upset the wedding, and (2) the singer responded to that by insulting "you", which is presumably one or more of the bride, the groom, and the guests. But I think specifying that the singer has crashed his ex-girlfriend's wedding is already enough that you deserve to fail if your answer is "he says he's not upset, so what he means is that he's not upset". It's not any kind of leap to guess that the bride's ex-boyfriend's toast might cause a scene at a wedding - that's why the bride's ex-boyfriends are never invited. (The question has already provided every word of the toast that appears in the song.) See also the sidethread comment by mikeruiz, noting that o1-pro reproduces the rest of the lyrics to The Victory, but gets the question wrong anyway.
