If you link an emotion to an unwanted experience or behaviour. Swish is the process to disrupt that link. For example, linking the act of "putting your hand to your face with a cigarette" to a feeling of pleasure. Tony Robbins was using this technique to help smokers quit. He would lock them with him in a hotel room and make them smoke many many many cigarettes. When they didn't want to smoke anyone, he would scare them and scream at them. He wanted them to associate smoking with disgust and fear.
