perfunctory interjection

The mindless, meaningless, random and irritating interposition of a word or words into a conversational narrative or appended to it.

"So I said - like - who does she think she is?"
"I had my head in the toilet - you know - and he jumped me."
"There were plenty of busty babes on the beach - and whatnot."
"A perfunctory interjection is - like - mind-numbingly irritating."
