trivolous banter 

Activities or chat that are incredibly trivial, useless, unnecessary, frivolous and a complete waste of ones time.

Example: A person calls you on the phone and begins to ramble on and on about themselves or attempts to explain an event that took place, you stop them during their conversation and say "I don't want to here your trivolous banter".
