noun: a term of endearment used among friends on the early New York Hardcore (punk) scene in the early to mid-1980s, usually preceded by the words "yo, yo".
origin: derived from "Egg Bo" a trademarked breakfast sandwich from "Bojangles of America" Restaurant. The expression likely came into use on road trips to out-of-town punk shows. Hungry band members would spot a roadside Bojangles and shout "YO-YO-EGGBO" indicating a desire to stop for food.
"Yo Yo Eggbo" is also a song by NYHC band "The Psychos" featuring Roger Miret, Billy Psycho, Stu Psycho, et al.
Yo, yo, Eggbo, I'm hungry.
Yo, yo, Eggbo, that was a crucial set the Psychos played last night!
EGBOK is an acronym for "Everything's Going to Be OK", originally coined by Robert Arthur and Ken Minyard on their radio show "Ken and Bob Company." and is also the personal motto of Dr. Ivan Misner, founder of BNI and Author who has popularized the acronym in his keynote presentations and blog posts.
"My life has been a mess lately, there have been more downs than ups."
"You've got through everything up until this point and you'll get through this too, EGBOK."
