"inside the beltline." it's a term referring to the people who live in Raleigh, North Carolina. It is where the houses are usually nicer and the property values are higher. It's opposite it otb, "outside the beltline," where the property values are low. people who live inside the beltline are usually of a higher class than the ones outside. Very powerful three letters, because whether or not you live itb or not is what you get judged upon in the Raleigh society.

Ex:

son: "dad I met a new friend at school today, he's really cool and nice but....

Dad: "but what?"

Son: "he lives outside the beltline"

dad: oh. too bad, if only he lived itb
