'You get on my wick!'

We all know that to get on someone's 'wick' is to annoy them. Where does the saying derive from - what has the 'wick' got to do with anything?

Never heard the phrase in the U.S. Is it regional? Or perhaps cricket-related, a vocabulary that bewilders us here?

get on one's wick/t i t s vb British
to irritate, annoy or vex. The 'wick' in question, unknown to many speakers, is a now rather archaic shortening of hampton wick, rhyming slang for prick (which is nowadays more usually shortened to hampton). In spite of the implied gender difference, both versions of the expression are used indiscriminately by both men and women.

'It really gets on my t i t s when someone calls me a career woman.'
