“You can't rush the Jack.”
jack 在負面的粗俗語裡面＝jack shit＝anything = nothing = everything.
You don't know jack = you don't know jack shit = you don't know nothing at all = you dumb ass.
You cannot rush jack = you should not rush anyone = you rush no one = you don't run no one
You cannot rush the jack = you don't rush no one, particularly me.
