When someone is being an extremely large downer, and is complaining, therefore ruining everyone elses good time as
well. Can be elaborated on by adding statements such as "
Stop eating all the
fun" and "Why do you have to eat all the good-time that exists in this room?"
Can also happen when the person is not saying anything but just acting extremely mopey and not contributing to the conversation.
Girl: "This
party is so lame. I'm so hungry and the
music here sucks. We should leave. Aren't you hungry? Don't you think tonight was crappy?"
Guy: "God stop being such a downasaur and eating everyone else's good time!"
