As everyone said, Wings are a must (Buffalo Wings or Hot Wings). Usually snacks are typical, so veggies and ranch or chips and salsa. You could always make a 7ish-layer dip.
I think the general rule is if it seems healthy, you're probably doing it wrong.
You also need beer. Here, I don't think you're wrong for being a little less realistic. The most common beer would be Budweiser or Miller, but I almost never drink that so I don't think a cheap British beer would be strange. Just make sure it's a Lager, ideally a Pilsner. If you get Bud, drink it very cold because, otherwise, you might have to taste it.
