"Grok" is quite commonly used verb which comes from a made up concept in Heinlein's "Stranger in a Strange land".

Grok is certainly a standard part of my lexicon.

what about grep?

Comes from the ed command ‘g/re/p’ (g: for each line matching; re: regular expression; p: print)

generalized regular expression processor ?

I reach for funner so often it's in my wordbag.
