Bippy - Silly word used on the comedy variety ROWAN & MARTIN'S LAUGH-IN/NBC/ 1968-73. During one episode of the program, the audience got some insight as to what a "Bippy" was: 

Dick:	May the Good Fairy sprinkle stardust on your bippy.
Dan:	Just a minute now. I've been meaning to ask you; what's a bippy?
Dick:	It's a baby bip.
Dan:	Then what's a bip?
Dick:	It's a big bippy.
Dan:	Are you sure?
Dick:	You bet your sweet bippy, I'm sure!

The "Bippy" word later inspired the title of the Rowan & Martin film The Maltese Bippy (1969). Once Liberace said "I bet my sweet bippy and lost it!"
