Señora diabla

[Hina Muqadas]

Literally a direct translation of Miss Devil. This is a term used to describe the types of spanish teachers that are overly materialistic and highly [judgemental] - the types of things you might see in a [spawn of the devil]. Because Señora Diabla is so materialistic and judgemental, she comes off as highly unattractive and therefore does not have kids or a husband even at the age of 45.
It also kind of refers to the general idea that spanish is the devils language, and therefore the [spanish teacher] IS literally a direct spawn of the devil.
