Comments: The form mutx-urdin probably reflects vowel assimilation (o > u) and expressive palatalization (tz > tx). Since lexicographers have avoided these words, due to their obscene nature, it is difficult to find detailed information about dialectal variants, etc. If the Bsq-NC comparison is valid, the original meaning was ‘pubic hair’ (cf. Burushaski *=múś-ki) > related meanings.
