dad jimmit
A loud, messy way to show you're really ticked off, but not so much that you need to yell god dammit. It came from the southeast in the late 90s and is like a cousin to dad gum.
Your brother spilled cereal on your brand new shoes and you yell dad jimmit at him.
Your mom burns the pancakes and you go dad jimmit in the kitchen.
You drop your phone in the toilet and scream dad jimmit at the universe.
