I made Jeremiah the frog's catchphrase "bullfrog" as an obvious reference to the song. I also admittedly got kinda dark with Lucky's catchphrase "kill me", assuming he's always in pain.
Nana:
-Hit me (And it actually spread to Monty)
-No evil!
-Pansear
Monty:
-GRAND DAD
Caroline:
-NUTSHACK
Muffy:
-Nikonikoni!
I don't remember the name but I remember telling a villager "LMAO KILL ME"
The greetings are funny too. I had Blanche say "Eat my ***" and Nana with "Fist me daddy" and "Femonkey here!"
and Caroline with "It's the nutshack!"
Gwen with "Fabulous"
Giving Ava "i guess...." was funny
another favorite Sylvia saying "ugh"
i'll never forget when I one time made julian say daddy and it spread to almost every ****ing villager
i forget all my other good ones but im sure there is more lol
