A mild expression of surprise, annoyance, anger, disappointment, etc. (The rhyming word "Louise" is added to give emphasis to "jeez," a minced oath for "Jesus.") Jeez Louise, Tom, don't you think you could have warned me before you turned on the sprinklers? Oh, jeez Louise, not again! That's the third time this month that the car battery has died. Jeez Louise, don't sneak up on me like that! You nearly gave me a heart attack!
