Is it the ＜Wait a minute! Why do you know all this?＞ part?

She says this in Japanese.
「 ちょい待ち！何その女子力高そうな知識！？ 」

(Spoken) ちょい待ち！
→ (Written) ちょっと待って。
　→ It means "Wait a minute." as it is.

(Spoken) 何その女子力高そうな知識！？
→ (Written) なぜあなたがそんな女子力の高い知識を持っているのですか？
　→ First of all, let's talk about 「女子力 (girls power)」.😅

女子力：
This is a slang term that has been in vogue in Japan for the past few years.
A person who exudes femininity in her knowledge, skills, actions, and behavior is said to have "女子力が高い (high girl power)".
It is similar to sex appeal for women, but face, style and age are not judged. Girl power is determined solely by the education one has acquired.

If you are good at cooking and housework, your girl power will be scored.
And if you're on top of nail art, beauty treatments, makeup, fashion, stylish trends, etc., you get super big points for girl power!
...Maybe. I'm a guy, so I don't know, but from what I've heard women say, the points seem to be determined by whether or not you have an advantage in appealing to other women rather than your intelligence.😅

It may seem counter-intuitive in a gender-free era, but it's something that women themselves have come up with, and they seem to be enjoying chatting about it, so I guess it's just a positive thing.

Now, just before, a man gives an explanation about the scent of herbs and jasmine.
Aromatherapy, what a very highly girl power topic.

So the woman said without thinking.
・何その女子力高そうな知識！？
『 Why do you have such knowledge that might make you more girl power !? 』
