An act of a large gathering of men cum over a wheat bread (preferably a cinnamon bun). The one who comes last will have to eat it.

A semi regular joke amongst male teenagers but nobody will admit if they ever done it.
- we got so bored yesterday that we actually did try runkbulle.
- ew, who got to eat it?

- Gösta, but don't tell him I said that.
