Nowadays, we tend to use one word instead of two to describe things about yukkuri (flapping, jumping and puffing up instead of flap_flap, jump_jump, puff_puff) so I think we should also update the rest for consistency.
"Madness" and "anti-yukkuritis" are basically the same, which describe the state of a yukkuri with a broken mind, the sole difference is that one is a general word and one is exclusive to yukkuri.
The "licking" part is pretty much straightforward.
P/s: I also think we should change rub_rub to rubbing though, but because there is already an implication for the contrary, I cannot propose it.
