Someone who’s as sweet as huckleberries? Or did Holly Golightly have a fondness for huckleberry jam?
A true friend, someone that’s right for the job. I didn’t know what Mercer was on about until I looked it up.
I see. Thank you.
In the context of the song, it’s also a pun on “Huckleberry Finn”. (The song is about a river, remember.) Huckleberry Finn=>Huckleberry Friend
