The monosyllable: what's your favorite?

My current favorite alternate word for 'vulva':

cunt

"female intercrural foramen," or, as some 18c. writers refer to it, "the monosyllable," M.E. cunte "female genitalia," akin to O.N. kunta, from P.Gmc. *kunton, of uncertain origin. Some suggest a link with L. cuneus "wedge," others to PIE base *geu- "hollow place," still others to PIE *gwen-, root of queen and Gk. gyne "woman." The form is similar to L. cunnus "female pudenda" (also, vulgarly, "a woman"), which is likewise of disputed origin, perhaps lit. "gash, slit," from PIE *sker- "to cut," or lit. "sheath," from PIE *kut-no-, from base *(s)keu- "to conceal, hide." First known reference in English is said to be c.1230 Oxford street name Gropecuntlane (attested through late 14c.), presumably a haunt of prostitutes. Avoided in public speech since 15c.; considered obscene since 17c.

From Online Etymology Dictionary

I absolutely adore that it could derive from the proto-Indo-European root for queen.
