aw hell yeah get marrieddddd
(note to the translators; I assume what you have as 'momo's code' there should be 'momo's outfit' or something similar; Japanese koode I think is a shortening of 'coordination' and means like a prepared thought-out outfit)
they're not telling you to ""censor"" your language; they're telling you to care about how the things you say can affect other people
'it's my mouth and I can say what I want with it' is not a very mature attitude to have; humble kindness is vastly more respectable
just so y'all know, stuffs (plural of stuff) is basically invalid in English; stuff is a mass noun and it's so generic you can't do the 'plural kinds of the mass noun' thing with it like you can with eg teas or gravels or whatever
