A hick was a derogatory term for someone of rural origin.
Prior to getting to know him, Malcolm Reed's initial impression of Trip Tucker was that the engineer was what Tucker's fellow Americans might call a hick. (ENT: "These Are the Voyages...")
In an alternate reality 2255, Nyota Uhura originally characterized James T. Kirk as "a dumb hick who only had sex with farm animals", only to have her first impression changed after Kirk correctly defined xenolinguistics. (Star Trek)
