My wife is the one I usually call Grasshopper in class. She has about 10 years of training, and is starting to get some of the deeper concepts I teach. "Grasshopper" comes out when she has a moment of cognitive dissonance over a principle.This was waaaaaaay back in the days when this was a brand new show
A friend of mine in that class was called Grasshopper... as for me....besides being called "Makiwara"..... I was also called "Stump Jumper"...the trials and tribulations of being the biggest kid in the class
"But, won't that leave me off-balance?"
"Only if you are off-balance when you do it, Grasshopper."
This is often followed by a swat to my shoulder. Okay, a punch. My classes are a bit informal.
