-ussy as a fuffix is not gender-specific. on top of that, bussy is already a form of -ussy, for the word boy. Boyussy does not work, due to y acting more like a vowel in context of the word as a whole.
using bussy in place of -ussy is never applicable. To use bussy means you are using Bussy as a descriptor, not as a noun (ex: dolphin bussy instead of dolphussy.) This is true for all words, even when spelling and/or pronunciation is not immediately obvious. (Ex: Ohio, while one thing might need to use Ohiobussy or Ohbussy, is spelled Ohussy, pronounced Oh-hussy. Some could argue for Ohiussy, pronounced Ohi-ussy, but that results in -ussy still being seperate from the word, not integrated.)
I hope this clarification helps!
