2) Connotation of someone from the United States.
A stereotypical American unlike me, is overweight not very intellectual and hated because of a stuck up attitude.
We do not see the appeal in using words such as: yank, bigot, and football (soccer). A stereotypical American believes that America in everyway is superior to any other country.
2) An American is to the world as New Jersey is to America.
For an example of a stereotypical American watch the show Diner's, Drive-In's, & Dives.
