sorry, brother. Had a gathering to help host.
It is precisely that term, which arguably came from just that author, that I used and use regularly. Oddly, I got it first from, of all people, a musician geek of the first order - Todd Rungren, who used it often when first appearing in the geek world and online. Mind you, I use it more in the bastardized sense of understanding thoroughly without knowing WHY I understand. There is, of course, the definition:
grok (grk)
tr.v. Slang grok·ked, grok·king, groks
To understand profoundly through intuition or empathy.
