when someone hates on you or tries to knock you off your grind you say “stay mad”

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.

A phrase used in response to an individual who is clearly mad and/or in denial of being mad

Can also be used as "Stay mad as fuck" to denote an individual who is beyond mad
