-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!

*** 'fistbump' emotes? Are you shitting me? You have become everything you ridiculed in the past.Every time you reach out your hand to your webcam and lower your voice there is a strong cringe feeling overflowing me like a zoo lock overflows the board. I really didn't care for all the hate you got before for streaming HS all the time since I quite enjoy the game myself. But this retarded crap is too much for me to bare. Goodbye Octavian we had a good run, will keep checking the sub to see if you repented from your sellout ways and returned to the true Kripp self. See you.
