cowabunga
interjection
(a yell of exhilaration, mainly used by surfers.)
Etymology: from Chief Thunderthud on the Howdy Doody Show
I remember “cowabunga” from “Snoopy” in the Charlie Brown cartoon strips...
Howdy Doody was right before I was born. But I’ve seen clips of that show on YouTube.
Kids were more innocent then... allowed to BE kids...
