From what I know, the slav squat is also an equivalent slang term.
In gym and fitness contexts, it would be an ass-to-grass squat.
The most polite way of expressing it would be to call it a deep squat, or a squat that's "past the parallel".
No I haven't nor is it high on my priority list; for that matter, I know little of Stoicism itself aside from a few aphorisms and axioms -- the di/tri-chotomy of control, the Four Virtues, etc.
As for why, I have the unfounded belief that Stoicism alone is too pacifistic thus is ill-equipped to handle malevolence at an interpersonal and societal level.
I would need to read and research to get some answers though.
I'm surprised to see that the ambient artist Stars of the Lid hasn't been mentioned.
It makes for good music to sleep, study, program and/or read a book to (most ambient music are unless they delve into the more abstract, avant garde realm).
I also like Hakobune and Chihei Hatakeyama. Nice warm tones.
And if I'm looking to get my blood pumping a bit, I've never gone wrong from recommendations from here: http://316144.tumblr.com/
