A pick up method guys use to belittle girls in order to sleep with them. It works on the priniciple that girls want to prove to guys how classy they are, when it may not always be the case.
Guy - "hey"
Girl (not interested) - "hi"
Guy - "nice dress"
Girl - "thanks it's a ____(insert designer name here)"
Guy - "oh really? i saw on just like it at k-mart" (walks away)
Girl - (trying to prove a point, chases guy) "actually..."
*great conversation starter and keeper as it encourages the girl to try to prove her point to the carefree guy* - the kmart complex.
