A quote from http://havemacwillblog.com/2009/04/11/10-words-you-dont-know/

"Jentacular. What could be more jentacular than the smell of bacon and eggs cooking on the stove and the rustle of cornflakes as you pour them into the bowl. The answer is: nothing, really, as long as you live in America or the UK. However, if you live in Scandinavia, such things are not jentacular at all - although the sight of sliced cheeses and cold meats on a plate certainly are. Jentacular means relating to breakfast."
