Here are two my grandmother (Northern Neck of Virginia) would say:
"Smells like something crawled up inside you and died" (if someone let loose with a real stinker)
"Fidgeting like you got an ant up your rear with a bed bug chasing it." (said of a hyperactive child, especially in church!)
She also used an expression which sounded like "Jummin," as in "Jummin knows, I've tried to talk to him but he won't listen." As best I can tell it's short for "The gentleman knows" or maybe "God knows" but I've never heard it outside of the Tidewater area.
Please remember to use a consistent name when you post. Messages with the "from" space blank, risk being deleted. "GUEST,guest" is not an acceptable user name.
