A sexual overtone can be sensed here! It is an obscene pun playing with the similarity in pronunciation between the first syllables of the word and the slang for female genitalia, 'cunt'.

This pun is also present in Shakespeare's Hamlet, when Hamlet to innocent Ophelia says, 'Do you think I meant country matters?'

Pun: a humorous use of a word in such a way as to suggest two or more of its meanings or the meaning of another word similar in sound. (definition from Merriam Webster)
