Ugly American (pejorative)

"Ugly American" is a stereotype depicting American citizens as exhibiting loud, arrogant, self-absorbed, demeaning, thoughtless, ignorant, and ethnocentric behavior mainly abroad, but also at home. Although the term is usually associated with or applied to travelers and tourists, it also applies to U.S. corporate businesses in the international arena.

The Collins English Dictionary defines an Ugly American as "a stereotypical representation of an American tourist as a brash and insensitive philistine." The Merriam-Webster dictionary’s definition is: "an American in a foreign country whose behavior is offensive to the people of that country."
