"Eve is going to San Fransisco for good! In order to celebrate I say we have a bbq at her house on Sunday, August 18th. She will think it is a going away party, but we all know better. Come around 4pm. If you feel like bringing food, do so."
I believe that the last sentence likely translates into, "Bring food, you ravenous bastards. You are like a plague of locusts, the way you eat."
