Regarding the term "Mad Robin", it can potentially lead to some conflict with the gender-free "larks" and "robins", so I'd personally lean towards using a new name, though I'm not strong in that belief. I can definitely imagine new dancers hearing the term and thinking that it refers to something that only the robins do.
There was discussion back in 2019 in the comments of Jeff Kaufman's blog [1] about this, when the term "robin" was being suggested about this. Some there suggested that the term "Mad Robin" could be replaced with "sashay" or "full sashay" from MWSD. Apparently "full sashay" was used until the 1950s, meaning the same motion as a Mad Robin, but is not used today, although "half sashay" still is. I can't vouch for the accuracy of that discussion though, since I haven't danced MWSD, and I certainly wasn't dancing in the 1950s.
