So, yes, Steve Reed asked me what "jackie dip" is and although I think I have mentioned it before I will explain again and it's just silly but here you go.
One time Lily was texting me about how "janky" something was and auto-correct thought she might be saying "jackie dip" and so that's how it came out and we decided that we liked the expression.
I get an image, when I hear it, of Jackie Onassis enjoying some chewing tobacco which is about the most bizarre and disturbing and simply wrong image I can think of so there you go.
I sincerely doubt that Merriam Webster will be adding it to their dictionary any time soon.
May your day be free of any and all jackie dip situations.
