At the end of one of the scenes, I have a character uttering the words, "Blow me." I searched for a phrase that was similar to "Bite me," meaning-wise (which of course is not slang from that decade at all). I searched for similar phrasing that was short and would get the point across and ended up with the blow me comment from an archive of 1920s slang. Now, my problem is that it doesn't sound right for the decade. I went with it because I couldn't think of anything else, but I'm finding it's throwing readers off a bit (as a recent reviewer just picked it out as quirky).
