The worst science teacher you could ever possible have. He never has any idea what hes doing, and to make up for his dull attitude, he attempts to do an experiment, but almost blows his face off.
n. (Australian) another word for a hat-stand, usually of a more extravagant variety.
Created because "hat-stand" was too boring and pragmatic; glenchley sounding far more sophistocated.
Feel free to hang up your stuff on the glenchley, old chap.
Haha, you've only got a hat-stand, we've got a glenchley, loser.
