The term "generalized abstract nonsense" is usually jokingly (and endearingly) applied to topics in mathematics of very high abstraction level, mostly category theory. It probably refers to the fact that some concepts in category theory can abstract away so far from the actual mathematical structures that are described as to lose all connection to the actual meat of the matter.

Contrary to popular belief, the no-nonsense black girl exhibits very much nonsensical behavior. She attempts to be a diverse member of society only to modestly reject others' praise of her realistic simulations of races that just are not her color. She has been known to suggest that you develop schitzophrenic habits and stay out of her thundering path. She's black, she's got a vagina, and she don't take none of dat silly ass nonsense sheeit. SHE WILL NOT CHANGE FOR YOU SO STOP TRYING SO HARD.
She's a No-nonsense black girl. She totally isn't changing her ways! Just look at her! No changes!
