Totally going bonkers. Bouncing off the walls hyperactivity. Very angry or happy. Based on a cult video of a ninja kitten dancing to the ska genre comedy song Flip out like a Ninja by the band Seven Seconds Of Love. Noted also for winning it's legal battle with the Coca-cola company over the song's use in a commercial.
