pack fudge or pack your bags
Saying to your partner they can either get their butt plugged or get the boot, because you're done with their whiny attitude and you're not going to let them walk all over you.
She: You either take it up the rear or I'm out. No more of your crap.
He: Pack fudge or pack your bags, I'm not your slave anymore.
Girl: I'm leaving. You're either getting butt-fucked or I'm gone.
