Re: ’Pop’ and ’raise’
One alternative definition of "pop" in this context could be "to have sex with a girl for her first time - take away her virginity". There is a slang phrase for this - "pop her cherry". It seems a little unlikely admittedly, in that it says he going to take these "wh*res" to the roost and pop some of them. If they are already being referred to by that term (wh*res), then it seems reasonable to assume that they are not virgins.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
