look up any word, like blumpkin:
 
1.
n. Person who grows up in a dense urban neighborhood ("downtown") as opposed to the growth-friendly suburbs.

Generally these people are socially awkward, unusually tense, and don't have close personal friends, but rather a large group of acquaintances they call "friends". They know everyone and no one at the same time.

Often flaky.
