When your character doesn't have lips or a mouth, or sometimes even any part out of which sound could possibly issue, in order to display the character is speaking, they will move their whole body around. Sometimes they just move once to indicate this, sometimes they're flailing wildly the whole time they're talking. Named after, of course, the tendency to do this when playing with dolls and action figures, since their mouths have no moving parts. Broader version of the Head Bob. If the character only talks through body language, see He Who Must Not Be Heard or Silent Bob
