Tips
usage
An AABB-form reduplication of 扭捏 (niǔniē, 'to be coy'). The doubled form intensifies and adds vividness. Almost always negative or impatient — used when someone is being annoyingly hesitant rather than charmingly shy.
memory
扭 'to twist' + 捏 'to pinch' — picture someone twisting their fingers and pinching their clothes nervously. That's exactly the body language the word evokes.
