An Americanism is a word, phrase or expression, commonly used in the United States, that has managed to escape from America to pollute the wider English language.

Any American-ized word or phrase, such as changing the spelling of words to sound as they mis-pronounce them, using 4 syllables or words where 1 would have sufficed, or inventing a new word or phrase because it sounds nicer (most commonly heard whenever they are 'fighting for peace' again).
Color, Armor, Boro, Aluminum, Leftenant (??), putting Z's instead of S's in words, or using clunky acronyms because they make a meaningful word (Arrogant American Alliance with Rightwing Goverments against Hope!, or Aaargh!)

Weapons Of Mass Destruction (Nukes), The Road Map (Plan), Freedom Fighters (terrorists we like), Terrorists (anyone we don't), Terrorist Suspect (anyone), Liberating <insert name of latest militarily inferior country that has weapons we supplied and something we want> in the Name of Peace and Democracy (slaughter and pillage <name>), Anti-American (anyone who disagrees), Anti-American Activist (anyone that tries to stop us), Our Friends and Allies in Europe (anyone with nukes), 9/11 (oops, apparently having nukes doesn't make you immune to retaliation), Pulling Together in the War for Democracy! (so c'mon England, lets make some NEW enemies!).

Brits who went to America killed the natives and were too stingy to pay the small tea tax. They went mad because of the tea deprivation and decided they wanted independence! They swore never ever to drink tea ever again.
