* 꿈뻑 (껌벅 is the standard word, but 꿈벅 and other variations are also used). It describes a light or the eyes blinking, once(껌벅) or multiple times(껌벅껌벅). 껌벅거리다 and 껌벅대다 are verbs describing repeated blinking. E.g. 동생은 졸린 듯이 눈을 껌벅거렸다. * 꿈쩍 (꼼짝 is more widely used. 꼼짝 sounds smaller and lighter, while 꿈쩍 is bigger and heavier) These are adverbs to describe a movement. They usually describe a single, slow movement, and used often in the negative. For example, a threatening "Don't move!" in movies is usually translated as "꼼짝 마", where 마 (말다) means "don't do". Examples: - 형은 세 시간 동안 꿈쩍도 안 하며 콤퓨터만 보고 있다 = My brother's been looking at the computer screen for three hours without even budging. - 발을 다쳐서 집에서 꼼짝도 못한다 = I'm housebound unable to move because of my injured foot. - 이대로 있으면 꼼짝없이 당한다 = If we stay put like this, we'll be screwed. (꼼짝없이 is a common adverb for "helplessly", "as if trapped", "with no way out", etc) * 쫍찍, 쫌마, 쫌맙 These are all useless non-words that probably not even one tenth of a percent of Koreans know. They are not listed even at the Naver dictionary for example, which allows ordinary people to list new slang terms they know.
