My favorite word in the English language is:
Fancy

It's supposed to indicate something a bit more elegant or superior, but it's such a goofy lookin' and sounding word it makes anything it's applied to automatically sound ridiculous.

For a while I collected ridiculous packages, mostly food, that included the word 'Fancy'.




Sometimes you can even find cans of stuff like generic green beans that boast of being 'Extra Fancy'.
