American culture is exposed to everyone due to the internet

I would define the American culture to be highly individualistic and xenophilic (to a point), cuisine generally being borrowed from Germany, France and Italy with most famously their Burgers

Christmas and Thanksgiving is very ingrained, and whilst you might claim Christmas is very universal (partly thanks to America) Halloween isn't, and it's mainly celebrated in USA and mostly USA only.

in America, community is more loose of a term than anywhere else, and independence is a must-have skill to have, this is why the trope of being kicked out as soon as possible from a household is so prevalent even though this doesn't seem to happen as much, or at all in other nations unless in very dire circumstances

America is generally depicted with the stereotypes of either southern conservative god-fearing people who attend protestant mass, or Californian liberals who seemingly accept anything and everything, enjoying luxury and being very upset about trivial issues, though due to individualism I can not think for the life of me a common dressing pattern, maybe military uniforms or suits

Due to how xenophilic and domineering American culture is, the media have essentially allowed for American culture to be available basically anywhere, mostly portraying itself within companies, holidays, local media and politics
