@nobodygattaknow I don't know if you're joking, but they are pretty common dance terms: https://en.wikipedia.org/wiki/Lead_and_follow . I'm far from a professional dancer, but I've used them all my life.
@FioreFire they're not really portraying tallness as "unfeminine" because they want to, they're dealing with the fact that a lot of cultures/societies treat it as such (unfairly, of course). It is a product of some fragile masculinity, with a lot of men feeling uncomfortable with girls taller than them, so, you know, those girls get treated poorly/rejected and it ends up becoming an "undesirable trait for a woman" (again, unfairly so).
Exposing that view of tallness as "unfeminine" and, seemingly, reverting this kind of prejudice seems to be a big part of this manga. Kiki feels like she HAS to lead (aka be "the man" of the pair) just cause she's taller, but she doesn't want to and Toribami wants to lead despite being short. So the message is basically "hey, even though it might be a little more difficult (in technical terms) to have the shorter person lead the dance you can do whatever you want and don't have to stick to stereotypes".
