A francophone posted something where they referred to the good people of Mastodon as "Mastochoux" and I am totally in love with the term.

For the non-francophones, "choux" means "cabbages" (and is a kind of pastry) but it is used as a term of affection, as in "mon petit chouchou." See https://untranslatable.ink/phrases/288/chouchou
