Something crap & nasty. The worst bit of the lot. The scaffy side.

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.

I'll be honest, I don't think anyone knows what it means anymore. Scholars maintain that the translation was lost hundreds of years ago.

A discarded, finished or almost finished, cigarette butt. Used, probably not often now, when, for example, some one is collecting butts out of a gutter, or off the footpath, or out of an ash tray.
