It's the same here in Australia with the "you know.." syndrome. I'm like, you know, guilty of it myself sometimes.
I guess we are getting away from profanity now, but something I find equally inane are clichés and business-speak. Sports people here habitually spout meaningless clichés as a matter of professional pride and don't quite know how to finish a sentence. Asked for a comment after a football match, they will string together something like "aw look, y'know its a game of 4 quarters and full credit to the opposition, their talls are prodigious but at the end of the day you have to walk the talk and capitalise on your opportunities, yeah no, so when I saw the big guy go up with his arms stretched out like a giant pair of testicles at the 27 minute mark in the final quarter, I knew we could bring home the bacon and like I said, winners are grinners but its a week to week proposition and yeah, so..."
