jibber-jabber

Excessive or meaningless talk.

And I would ask counsel to check his sense of humor at the door. My courtroom is a temple of decorum, and I do not tolerate jibber-jabber.

Douglas: Well done on passing the test, Jen... Yes, all those clumsy attempts at seduction. Don't tell me you couldn't see through them. They were a test to find out whether you really wanted to work for me or whether you just wanted to come up here for my body. Jen: Oh, no, no, no, no, no, not at all. Douglas: All right. Jen: No, physically you're just not the sort of man I go for. Douglas: Yeah, thanks, Jen. Jen: I go for the classically good-looking men: Blond, broad, and generally clean shaven. Douglas: Alright, yeah, enough of the jibber-jabber!

To talk excessively or meaninglessly.

Is my mind goin' on me or am I watching you jibber-jabber like some sort of jibberty box. Jibber-jabber on! Jibber-jabber on!
