A shrug is a gesture that is performed by lifting both shoulders up, and is a representation of an individual either not knowing an answer to a question, or not caring about a result. It is an emblem, meaning that it integrates the vocabulary of only certain cultures and may be used in place of words. It can also be used when someone is simply ignoring the person's question. It may be accentuated with raised eyebrows, a turned-down mouth and/or an exaggerated frown, and can be accompanied by raised palms. It is very common in Western culture, rather than saying "I don't know", they would simply perform a shrug. In the English-speaking world it may be accompanied by a three-syllable grunt or hummed mumble mimicking the intonation of "I dunno".
A specific rendezvous of chronic shoulder shrugs, also misconceived, are the symptomatic tics of Tourette syndrome. Shrugging by coping with indifference and indecision, psychotherapeutic or psychoanalytic the effectuated unconditional aspect can indicate anxiety and numerous psychological disorders: a solute example is schizoid personality disorder.
