can see the problem in my dojo. Someone says Sensei and all 3 heads pop up. My real little students called me "big" Sesnei and my son "little Sensei" but my son didn't like that much. So this is how I got my nickname SenseiLou. Our students call us Sensei or Shihan and add our name to it, so we all know the difference. I thought for sure you had something up your sleeve though.
