College campus... Hell no.

Did you ask them if they wanted Mel Gibson back?

I think Foster's has a lot in common with our Pabst Blue Ribbon.

I'll try to explain some of the things. Since it sort of makes sense in a weird way.

1) Amercian Culture has some eccentricities unique to us. Hence our culture could be made a party of (I guess that would apply to any culture)

2) Popcorn is primarily an American food. It's big over here and was invented here. It lends itself well as a snack food like chips (or crisps depending on where your from). Corn Dogs would be another food I'd expect to see at a big American Party as well as cotton candy. Bonus points awarded to anyone not in the US, throwing a US party, who cooks the food in beer (extra extra points if it's an American beer commonly sold like Budweiser or Miller). Apple Pie should be at these kinds of parties as well.

3) I like this level of satire. Kind of pokes fun at big companies. Plastic cups are cheap and they are usually colored red or blue, blue is a bit harder to find. Other color cups used to cost more as of a few months ago from where I am at. (I guess the plastic companies making the cups gave up on red and blue). Consequently the most bought cup for a party here in the US is red. Walmart and dollar stores have just started selling other colored cups just as cheap off of holidays and major events so in about 10 years US parties in non US countries might not make this a thing then. For those in the US I recommend buying your other color cups way before the event needs them (since places will mark up the price of those to match demand)

4) Every single time I see a celebrity they are in some kind of Basketball outfit. I mean we even have sports celebrities from non basketball sports wearing basketball gear.

I'd like to add my own extra suggestions for such parties:

-Fireworks
-All movies shown must have sex or violence, preferable both in the movie.

Popcorn originated in Peru, where it is still popular, but the first commercially successful popcorn machine was an American invention. (C. Cretors & Co. still makes the finest popcorn machines.) It's also popular in China. It's a party food when the party involves sitting around and watching a movie or television. Not so much so when the party is an active one.

The red plastic Solo cup was a fixture at every kegger I went to through 9 years of higher education. Except for green plastic Solo cups at St. Paddy's Day parties.

Beer brats are a sure thing at any party where the hosts are from Wisconsin. Potato salad, too. Wisconsin is the true home of real American party food.

Because basketball can be played on a driveway, it is often played at parties. Touch football requires a lawn, and baseball or softball requires a park and a safe boundary, because a foul ball or an overthrow will break windows.

Looks pretty damn 'Murican to me.

personally i prefer finnish parties. ="enough" beer and/or other alcohol. The rest dont really matter. Shame that as family man i dont really have time nor chance to do that sort of thing any more at all.

This is how we party in Germany (obviously)! ;)

I don't ever recall being in an "American party", but I've seen some French or Brazilian themed parties. And they always seem pretty silly to me, but I guess every party must have some kind of theme, so why not base it on some fake view on some culture, like Brazilian, French, Irish, Australian or American.

I didn't get the references to red plastic cups, I didn't realize they are an American thing anymore than e.g. orange or green cups would be. You learn something new every day. I'm surprised none of the American-themed parties had people dressed as rich Texan oil millionaires with big cowboy hats, isn't that the strongest American stereotype?

But then, what's with Americans celebrating their "roots" because their grand-grand-grand-grand-grand-mother came from Ireland or Italy? Or is that also just a stereotype fed to us by Hollywood movies, that Americans like to cherish their very distant non-American roots, as in having e.g. an Irish day where you wear some green and march on the streets as leprechauns?

Many times, those roots are not so distant, and they are carefully kept alive by people who grew up with ancestors who came from the "Old Country". Sometimes they preserve festive days that no longer have a following in their ancestor country, such as the huge Dyngus Day celebration put on by the Polish community in Buffalo. And sometimes they go to ridiculous extremes, such as dying the Chicago River green for St. Patrick's Day.

It's probably just a fad.
The tables can be easily turned on this matter with a single rhetorical question: What do most Americans imagine when they think of Mexican parties or Egyptian and Japanese people in general? I must ask.
What does basketball have to do with rap music?

Both have especially strong followings in the black community, to the point of having become a stereotype.
