If you want to censor any strong word, you can change it by random symbols like #$%&/()! just put the same amount of symbols than words and grown-ups will going to figure out the words and kids will always assume that is a bad word but they will never figure out wich one is.
It's a common rule for comics, especially for those that are targeted for all audiences.
Even bitch can be censored for kids if you don't want to kids say something like bitch in any way, just change it to B#tch or just put #%$# to completely censor the word.
