Adj. This expression is a play on the
similarity between the word "
thorough", and "
Thoreau", the last name of famed author Henry David Thoreau. "Henry David" as a phrase can be used to replace the word "thorough" in any common sentence.
For instance, say you are in the middle of a board room discussion with a bunch of corporate executives. You could
chime in and say "I've done a very Henry David analysis of these reports, and things are looking good."
By adding "
ly", this can also be made into an adverb. "I Henry Davidly enjoyed our evening.
Let's do this again!"
