A dance, beginning with the "Move It Like Bernie", and slowly progressing to a point where a person has lifted both their arms up parallel to the ground (resembling a bird), while simultaneously bobbing their head and making bird sounds. It is also appropriate for a person to twitch their arms as if they were shaking their wings.
