gyroscopic (adj.) related to an apparatus consisting of a rotating wheel so mounted that its axis can turn freely in certain or all directions, and capable of maintaining the same absolute direction in space in spite of movements of the mountings and surrounding parts: used to maintain equilibrium, determine direction, etc.
“Mark eyed Cassie for another moment, then gave her a nod; she had apparently passed some private test. He moved on to me. He was somewhere in his mid-twenties, with a long fair ponytail and a narrow, foxy face with very green, very intense eyes. Men like him – men who are obviously interested purely in what they think of other people, not in what other people think of them – have always made me violently insecure. They have a kind of gyroscopic certainty that makes me feel bumbling, affected, spineless, in the wrong place in the wrong clothes.”
