I happened to be watching an old Flinstone cartoon with the kids and thought - "Hey, here's my 'Y' word." So thought I would do a little research.
Yabba-Dabba-Doo, is the catchphrase of Fred Flinstone, the patriarch of the Flinstone cartoons. I found that the phrase was actually adapted from a old Brylcream jingle - "A Little Dab'll Do Ya!")
Even more interesting is the definition from the Urban Dictionary. As this is a family blog, check out the meaning of Yabba-Dabba-Doo for yourself!
What ever it means to you ...Have a good day!
