UIK

acronym for "unfriendly indie kid", these are the often pretentious people in skinny jeans, Ray-bans, plaid shirts, flat slouch boots, baggy cardigans and American Apparel everything else. Pronounced "yoo-ick."

Aw, look at the little UIKs swarming around in that concert of a band that no one's heard of!
