In desperation I googled 'catch phrases' which brought up a lot of sites that detail hundreds if not thousands and I went through a site I liked and picked some out.
Sometimes I use phrases that link with the animal the villager is - sheep: fair dinkum, Aussie bound, pullyover, G'day mate, lamb chops. A chicken: KFC rules, pull my feathers, ad infinitum. I have tried French phrases and Japanese ones, the latter not particularly successful as I often can't remember what the phrase meant! I sometimes give cranky males the phrase 'I need a hug' .
