Maybe somebody has already done this in this long thread, but if not, I would like to point out that 'Americanism' is a word that's been around a long time, and it means 'being proud of America, or of being an American.'

Nowadays, we tend to frown on it, regarding it as a form a chauvinism. But sometimes, when I see the kindness or the courage of Americans around me, I'm proud to be American myself.

For example, when the tornado destroyed the hospital in Joplin, Missouri, the staff showed real heroism in saving the patients. (I bet that never made the British press.)

However that may be, Americanism is not what Mrzzy seemed to think, which is 'being a drunken thug.'

By the way, isn't it odd that the British use an Irish name (hooligan) for its home-grown louts?
