I hate... HATE... the interstitial "right". A lot of people will use the word "right" at the end of a sentence to look for confirmation they're understood, or validation on their point... Example:
"Hey, you're still bowling tonight, right?"
That's perfectly fine.
But what I hate is when it's in the middle, simply replacing a pause or the "uhm" sound or something.
"I was walking down the road, right, and this car drove by and beeped for no reason."
It kind of infuriates me, and I don't even know why.
