扣脚女汉
[kòu jiăo nǚ hàn]
'Feet-scratching tomboy'. In China, 'female hanyu' is used to describe girls who act tough and more masculine. While 'feet scratching' is seen as uncivilized behavior. So the overall expression may hint she is unconventional with boyish manners and doesn't mind if others consider her unfeminine or unrefined.
