A pinch is a grip of a flexible object in which a portion is taken between two fingers, until it hurts, or something of resemblance and squeezed so the gripped portion of the object is lifted from its normal level.
The closer to the thumb the other finger is located, the stronger the pinch.
Pinching the skin can result in pinch marks, a cutaneous condition, and when on the ears or in the genital region of male children may be suggestive of child abuse.
