A "Cheese Grater" is someone of incredibly low inteligence. The term Cheese Grater comes from the belief that all inteligent people start with a base I.Q. Like cheese (you start with so much), and these imbeciles come along and shred every precious point from you; simmilarly to how one grates a cheese block.

From STEM, an abbreviation short for "Science, Technology, Engineering and Mathematics", a STEMlord is a pejorative term for a particular kind of person who has studied in these areas at university or works in these fields who holds a pretentious, condescending attitude to anyone who has studied in any other fields, particularly the Arts and Humanities. They typically believe themselves to be more "intelligent" and "rational", while generally remaining incredibly ignorant outside of their areas of expertise and having the charisma of a rotting pig's backside.
