is a form of nonverbal communication
that is performed by lifting both shoulders up, and is an indication of an individual either not knowing an answer to a question, or not caring about a result. It may be accentuated with raised eyebrows and/or an exaggerated frown. In the English-speaking world it may be accompanied by a three syllable grunt or hummed mumble mimicking the intonation of "I dunno". The shrug is relatively absent from Eastern culture.
