"Time Warp"

Okay, "Time Warp" from Rocky Horror Picture Show was on my XM Radio this morning. I've always missed a crucial lyric in this song and was wondering if someone could help me:

"It's just a jump to the left
And then a step to the right
Put your hands on your hips
And bring your knees in tight
It's a _________?
That really drives you insa-a-a-a-ane
Let's do the Time Warp again."

Help!
