The female shrugging emoji, used identically for indifference or uncertainty. Trivia: gender-specific shrug emoji see relatively light use compared to the base version, reinforcing a broader pattern across all these gestural emoji trios — the neutral or historically-default form tends to dominate real-world usage over explicitly gendered ones.
