I've noticed that some people have strange phrases or idioms that are part of their verbal repertoire. These phrases are often unique to them.  Here are a few from my mother:
"Gee mini-Christmas!" 
Father:  The Donaldsons' house was flooded.  The lost everything in their basement.
Mother:  Gee mini-Christmas!  That's awful!
  
"Golly Gee"
Father:  Would you like to go out for pizza?
Mother:  Golly Gee, that sounds great!
"Let’s blow this popsicle stand!"
Father:  We better hit the road if we want to make it church on time.
Mother: Let's blow this popsicle stand!
"It will be an adventure!"
Doctor:  Post-op you will have no use of your right arm for three months.
Mother:  It will be an adventure!
I occasionally use "Let's blow this popsicle stand!"  I also use "ya der ay-nah-hey" occasionally.
Wife: I think that we should wait until the weekend to go to the grocery store.
Me: ya der ay-nah-hey [sounds good].
Do you or people you know have any phrases/idioms that seem unique?
