using examples like "Wulky Wilkinsen" and post utopianism made no sense to me

That's sort of the point. The words "post utopianism" and "colonial alienation" don't mean anything.

You may have been exposed to enough american culture by tv, movie, shows and books to not get overwhelmed by them?

Most movies and even tv-shows that run in Germany are actually American. Books might be more of a problem, but if it's a classic like the Christmas Carole, there is a Simpsons episode about it :)
