I have to admit that's somewhat confusing, road-runner, as the word itself appears to be contra-duck-tory. At the beginning we have 'woper', implying great size, but the ending 'kin' seems to be a dim-initiative. We have to ask, is this large or small? Is it at the larger end of small, or, as I believe, at the smaller end of large? 
No, no, no.
Woman, you see, but the end of
woman is
man, and that is masculine, so you change that to
person, and get
woperson, but the end of
person is
son, which is also masculine, so you change that to the gender-neutral
kin, so
perkin and hence
woperkin. Also Perkinchester, Perkinchester United, Perkinchester City, Perkinfredd Perkinn's Earth Band, and possibly Perkinotea.
