i Register
In some senses, mimsy is marked as slang, vulgar. Watch for register when choosing this word.
adj
A nonce word in Lewis Carroll's Jabberwocky
’Twas brillig, and the slithy toves / Did gyre and gimble in the wade^([sic – meaning wabe]); / All mimsy were the borogoves, / And the mome raths outgrabe.
Down he sank in a chair—ran his hands through his hair— / And chanted in mimsiest tones
noun
The vagina.
It seems plastic surgery for men is catching up in the lunacy stakes with the world of female plastic surgery, a place where you can fly to LA and get the shape of your vagina changed: what constitutes an appealingly shaped mimsy is something else to be filed under "unanswered questions", next to the one about who wants a huge pair of balls.
