A nick name for THE crappest music teacher on Earth. Few people suffer from Mandrobe and are actually taught music at high school, but the unfortunate few have to suffer the BO, terrible singing, imensly bad keyboard playing and of course the testicle chair.

Those who have never met the beast will not understand this but if you have had the misfortune to have met Mandrobe you'll know exactly what I mean...
Hamish: Mandrobe was chasing me again down the music corridor.
Ron: Really? Why? was it to make you sing for her?
Hamish: No worse, she wanted me to push her testicle chair!
