Ameritrash is port-manteau of "American trash" meant as a pejorative towards a genre of American boardgames. In general, this connotes games that highly emphasize theme (i.e. story, background, motivation, etc), player to player conflict, and usually feature a moderate to high element of luck. This is used in contrast to Eurogames.
