Well, you all made me laugh this cold Chicago morning as the first El of the day awoke me [grumpily] in my hotel. (The next six passed by in the succeeding two minutes.

I particularly like lacosapient. I only saw the definition at first. "Okay, I made that up" was revealed only upon scrolling down.

Aphoristic, pithy and compendious seem to more imply quick wit rather than wisdom necessarily. Prudent seems to have more of a sense of caution than wisdom and laconic could refer to the farmer who confines his speech to yep and nope.

Knowing I haven't overlooked the obvious helps. I vote for coining one. It would be a lot more useful than a lot of coinage. That said, lacosapient might be just a bit stilted.
