Note to Self: Eliminate the word "Jack" from curses

I was getting ready to go on a short weekend trip with the boys and I ran into a little problem with my conversational cursing.

Me: I have so much to pack! I haven't even started.

Friend: Are you packing for the kids, too?

Me: Yeah, and I haven't packed jack shit. Well, I actually did pack Jack's shit, but nothing else.

Now "jackass" is off limits, too. I prefer "dipshit", anyway.
