Bonhomie is the warm, easy friendliness that sits over a group — people smiling, teasing kindly, making room for each other. It is not one person's private kindness so much as the mood between people: a dinner that feels loose and good, a team that actually likes being in the same room. The word is borrowed from French and still feels a little dressed-up in English. You meet it in writing, in speeches, in newspaper sketches of a party, more than in everyday chat. A friend would just say everyone was really friendly. When people do use it, they sometimes stretch it: 'forced bonhomie' means the smiles are on the surface and the warmth is not quite real. That hedge matters. True bonhomie is easy; fake bonhomie is work.

和樂、熱絡的氣氛（書面、帶點法文腔）。日常比較會說「大家很合、很熱絡」。不是「好家庭」——字面上有 homme（人），不是 home（家）。
