Nebby is a teacher who shows no discipline, and in no way at all, practises what he preaches. His favourtite sayings include 'Gordon Bennet', 'Your Going On Call', and despite being a teacher of religon 'Jesus Christ! God help me with these Bastards!!!!'. These lines have become so legendary, that they have been made part of the innaugeral 'Nebby Song', performed by the equally legendary Pear Tree Farms.
Nebby is also deserving of his own verb, 'To do a Nebby' or 'to complete a Neb movement' (Normally flailing your arms around in the rough direction of the deputy headmaster's office)To have a 'Nebby shower' means that you sit on the front row of class and get soaked by his extravagant oral juices while talking, seemingly to no-one, about The Rt. Reverend Desmond Tutu.
I had a Nebby shower yesterday; It was delicious
Possible origin: Root word Neb means beak or similar protrusion from the head. Neb nose is also a term with the same meaning as nebby. Therefore a Nebby neb nose is always poking his/her "beak" where it shouldn't be.
James: thats impossible
Max: well afterall, i am nebby.
