Mine's bivouac, for no other reason other than I think it roles of the tongue nicely; 'nice' now there's an overly used word.
fuck its so old, and theres no real known place of origin and it's just so fucking versitile but there are many good words
I also love onomatopaeic words, like 'fizzle', 'wallop' and 'clash'. Ooh, I like it..... I like English languagey words; hyperbole, homophone, pronoun, and oddly enough, onomatopaeia
Onomatopaeia and Discombobulated are both excellent! Cathedral is always the first that springs to mind for me. Spatula has a nice ring to it, never get to use it though, I call spatulas 'flippers'. Some others which are cropping up; Loop and Luna. Hydrogen. Simplicity.
