It's funny how some words weave themselves into our vernacular.
When someone mentions "Kum Ba Yah," they're probably referring to a group hug, or poking fun at the sensitivity of a situation.
"Well, we're getting along so well now that we should all sit around the campfire and sing 'Kum Ba Yah.' "
"Kum Ba Yah" is actually a 19th century African-American folk song, originating among the Gullah, a group descended from enslaved Africans living on the Sea Islands of South Carolina and Georgia.
The song enjoyed newfound popularity in the '60s folk movement, when Joan Baez recorded it in 1962. The song became associated with the civil rights struggle of that decade.
