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.

Sending someone to the puta que pariu is sending someone to a whore ("puta") that has had a baby ("que pariu"). It is assumed that this whore shall have a new baby with her new client, which is a rather unfortunate something to wish your friends.
