To go Flintstones is when you ride somewhere in a car with two couples and the guys sit in the front and the girls in back, ala Fred, Barney, Wilma, and Betty. Some women find this arrangement to be degrading.
Hey baby, when we drive to Vegas next week, can we go Flintstones so I can talk to Chad?
One who is exceptionally stupid or ignorant, a moron on a grand scale. Formed from the Germanword über as in Nietzsche's concept of the übermensch in Also sprach Zarathustra. Used recently conjoined with other adjectives, as in über cool, übersexy, and über moron.
It takes that überidiot an hour and a half to watch 60 Minutes.
