Other forms: shrugged; shrugging; shrugs
To shrug is to raise your shoulders slightly, often to show that you're unsure or indifferent, like when you don't know the answer to a question.
A shrug is a gesture that can convey a lot without words. You might shrug if you're uncertain about the plans a friend is suggesting. You may also find yourself shrugging in response to a question that you don't know the answer to or one that you don't care enough about to answer. A shrug can suggest indifference to a person or situation that you might normally find stressful, showing that you have simply decided it's not worth getting worked up over.
