Guess it depends on the frequency with which the word is used I think, whether is could be a personal cliché or a verbal tic.

I have a cousin who uses "hoe heet et" (what's it) really at such high frequency during converstions that had to ask him if he could lower it. He couldn't. That's definitely a verbal tic.
(lots of ticcies around )
