An acronym for a weapon named "Ultra Ice Katana" in an online game known as Adventure Quest.
UIK is better than Chill Ripper.
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!
