Up here in the North we say Uffda (pronounced ooff duh) which means many things but mostly it's an exclamation. Like if you just got done walking across a cold parking lot you may come in the door stamp your feet and say "Uffda, it's cold out der den (same as there, then)." You can also expound on Uffda by saying "Uffda be golly dontcha know."
Also we ask if you want to come with. For example, "Hey der I'm gonna go and get some dinner, wanna come with?"
