I hope your sensei is a ninjer so he can flip out and take this fucker out with his ninjitsu for missing 3 tiles. That's if he hasn't commited seppuku with a frisbee like he should have for this disgraceful display.
Commiting seppuku by frisbee is actually a centuries-old technique that can only be mastered by a Third-Generation practioner who comes from a family that has practiced the technique for many years.
