Irony is when you think something is going to happen and then the exact opposite happens. I do think the words in the song are actually ironic. In the song ironic, she says wouldn’t it be ironic if it rained on your wedding day because that is really ironic for that to be your special day and for it to be ruined. It is also ironic when a man rides a plane for the first time and it crashes, because he never went on a plane because he thought it would crash. When he rides it, it crashed therefore this is ironic.
