Edit
A yukkuri (usually koyukkuri) dancing. A yukkuri's dance is usually a mix of bottom wiggling, stretching, and rolling, often accompanied by singing.
Also see the poo poo dance, a special type of dance used to help koyukkuri shit.
Some koyukkuris will approach humans just to show them their dance. This is because they believe humans can take it easy by seeing them dance and would expect to be praised afterwards. If they're shitheads they might also expect a reward. But regardless of shithead or not they'll usually complain when a human doesn't return their dance with compliments. Unfortunately, a pastry wiggling their ass is just annoying for humans and so it's often returned with abuse instead.
Nobody here but us chickens!
