A proverb meaning that repeated refusals or protests can actually indicate affection or liking; 'saying no' may really mean 'yes'.
あの二人、いつも口げんかばかりしてるけど、嫌よ嫌よも好きのうちだよね。
Those two are always bickering, but 'saying no' often means 's/he likes you', right?
彼女は『絶対行きたくない』って言っているけど、嫌よ嫌よも好きのうちかもしれない。
She keeps saying 'I absolutely don't want to go', but that might just be her way of showing interest.
昔から『嫌よ嫌よも好きのうち』という諺があるから、場面によっては本心と逆のことを言うこともある。
There is an old saying, 'no often means yes', so sometimes people say the opposite of what they truly feel.
