Where did it come from? I don't know. The strange and beautiful imagination of my daughter. One day she was bouncing on the guest bed while I was using the bathroom, and then I heard her say Bounce like a Chicky-Munk! Bounce like a Chicky-Munk!
When I came out, she had her arms folded with her hands in her armpits, like she was imitating a chicken, and was bouncing up and down on the bed like a maniac. So now it's the chant that accompanies every bouncing session, even when she's just jumping on the carpet or in a puddle, or wherever else the spirit moves her.
So enjoy your Friday, and don't forget to bounce like a Chicky-Munk, if you feel so moved.
