I don't care for that word much either. But it's normalized in our culture so I'm used to it which makes it less abrasive. Another problem with "grok" is that I can't convince myself of how to pronounce it. This fact alone is probably causes half of the internal discord I feel when I try to verbalize it internally (does it rhyme with rock or broke?). Also its spelling doesn't have any precedent in English, so every time I see it my subconscious pattern matching system goes haywire.

You know when you read or hear something that is contradictory, or something that is just painfully wrong, and you can almost feel your psyche twinge as it recognizes the error? I get that feeling every time I see this word. Perhaps that's just me.
