I think you should call it by the local native name for leftover food (which of course you researched), which is Whadawigonna. As in "whadawigonna do with all this?"
Yes, I can hear the sound of tom-toms emanating from a circle of tepees now, as the pipe is passed around, the dancers whirl, dressed as giant scrub turkeys and native spirits, looking forward to a feast of whadawigonna.
