When I look up the word "heady" in the dictionary, it seems that the main definition is "tending to intoxicate." Farther down, "having an exhilarating effect" and "intellectually demanding" are also definitions.
For some reason, when I have heard this word used, I have associated it with meaning something like "too intellectual or philosophical; not practical enough" or "too much thinking and not enough practical application."
My questions are: 1) does anyone else understand this word like I do? and 2) if not, what are some similar terms that I could use instead?
