pause to collect your thoughts

Dan remembers that in college he had some stoner acquaintances who would use the word f---in in all sentence pauses, instead of "um."

They would be like: "F---in ... let's get something to eat!"

I've noticed, over the past five years, that our president seems to do the same think with the phrase "nine-eleven."

He's like, "Nine-eleven... we need some more pretzels up in this oval office."
"Is that show on tonight...nine-eleven....what's it called? Oh, West Wing."
"Well I'll answer your question... nine-eleven... and I'll say that...nine-eleven...we're doing our best to secure this nation's ports."

Am i wrong here?
