Chimamanda Ngozi Adichie said this quote

Some people will say, “Oh, but women have the real power, bottom power.” And for non-Nigerians, “bottom power” is an expression in which I suppose means something like a woman who uses her sexuality to get favors from men. But “bottom power” is not power at all. Bottom power means that a woman simply has a good root to tap into, from time to time, somebody else’s power. And then of course we have to wonder when that somebody else is in a bad mood, or sick, or impotent.
