"Weighty Brained"    

Here's Another 2 to 4 word phrase I Like.    

Post your own liked phrase. Or someone else's with or without comment.   

Is Elon Musk "Weighty Brained." It's clear he is often "Light Hearted." Is it not equally clear that he is often  "Weighty Brained"? Or is he always "Weighty Brained," even when he is light hearted? Or is "weighty" the problem and should it be "heavy," the true opposite of "light"--which "weighty" is not. 

But, "heavy" brained is all wrong: "heavy hearted" is a very common expression and carries negative "vibes," to use a word Elon likes. He is definitely not heavy brained. 

Weighty Brained, it is. 
(and light-hearted, too.)
