你咬我呀咬就咬呗
[nĭ yăo wŏ yā yăo jiù yăo bei]
'Ni yao wo ya yao jiu yao bei', which means casually 'Bite me if you will'. Suggesting an unconcerned attitude or indifference, almost challenging another’s action without fear or care of consequences. However, sometimes it is also seen playfully when among close friends or couples.
