Are you aware of fundament to mean buttocks or anus?
I saw this in LEO and thought it must be missing a BE tag. OALD and CALD don't have it; however, both AHDE and Merriam Webster do. I find a handful of hits online for things like "bite him in the fundament" and "kick him in the fundament," while "a naked fundament" mainly seems to be on sites that copied the example from Merriam Webster.
Does anyone else, especially native speakers of AE, find this word suspect? If nothing else, it would seem to warrant some kind of "infrequent" tag; fundament certainly is not as common as duff, butt or behind as a possible translation for Hintern. Or possibly it's some kind of formal term used in anatomy texts; that would fit with buttocks and anus. In which case, it might not be a good match with more colloquial German terms like Gesäß and Hintern.
