This is the "cellar door" phenomenon. Turns out that when you divorce certain names or phrases from their meanings, names for mundane or gross things can actually sound quite beautiful.

The canonical example is "cellar door", which is frequently considered one of the most beautiful strings of syllables in the English language. Tolkien was one of its most famous proponents, but a good many writers have said the same thing. And another has said the same about "salad or" (as in "would you like salad or roast vegetables with that?"), which is almost the same thing.

Just forget about the meaning and respell it as "Selador" (it's better if you pronounce "cellar door" with a non-rhotic accent), and you've got a quite pleasant fantasy name.

That's also long been a joke name in the US referring to people who are less-educated http://www.snopes.com/racial/language/names.asp
