You’re pretty well-grounded

This a nice malaphor word blend of “grounded” (sensible) and “well-rounded” (having desirably varied abilities).  Perhaps the speaker meant to meld the two meanings into a new word, but probably just mixed rounded and grounded, which is easy to do.  A big thanks to my cousins from Down Under, Manny Manatakis for uttering this gem and Gemma Martinez for hearing it and passing it on.
