When we were running late, my Dad would hurry us along by saying "We ought to be halfway to Omaha by now!" Didn't matter where we were going but that was the expression to hurry up. It came from his childhood living on a farm when his father would hurry the boys to load the wagon to take produce to the market in Omaha, Tx. It just became the family saying for "hurry up". The funny part about it is that my husband, who is from South America, picked up the saying without knowing any of the family history. He just thinks it's an American idiom.
And in a reverse idiom usage, my husband has always used a South American expression when fed up or frustrated that roughly translates to "I'm just going to tie my head and leave." I have no idea what the "tie my head" part means but I've used that expression for the past 40 years.
