Lacertilia - A word so evil it was created by a teacher who wants to make

A word so evil it was created by a teacher who wants to make your life miserable and your grades even worse.

My teacher called me Lacertilia and I got a bad grade and a detention.

I heard my friend's teacher call him Lacertilia and he laughed until he fell over.

My brother got called Lacertilia and he ran out of the classroom screaming.
