I am trying not to take this post by young Mr ThunderDragon personally. Particularly as "grok" is from a sci-fi book published when I was a toddler. According to SearchSMB.com;
To grok (pronounced GRAHK)
something is to understand something so well that it is fully absorbed
into oneself. In Robert Heinlein's science-fiction novel of 1961, Stranger in a Strange Land,
the word is Martian and literally means "to drink" but metaphorically
means "to take it all in," to understand fully, or to "be at one with."
Today, grok sometimes is used to include acceptance as well as
comprehension - to "dig" or appreciate as well as to know.
Also, "My Generation" was the song of the screwed-up generation before mine. You know; the one which completed the evil work of the war generation; stealing the money of succeeding generations by creating an unfunded Welfare State.
If you want to insult your elders, TD, your generation might like to make up some words (and music) of its own.
