To grok is to know. If you really truly understand, then you grok it. You have become one with it and you have enveloped the meaning.

The word comes from the Martian word, "to drink". Yes, Martians. Robert A. Heinlein, the author of "Stranger in a Strange Land" gave us this word back in 1961 and the computer industry later adopted it as our own. Trekkies have used this word, along with Matt Groening so you know it has reached the pinnacle of geekdom.
