My two pennies worth...
People used to fill gaps in thought with 'um'. Now they use 'like', 'you know', etc.

The boyf counted my mum and she said 'you know' 147 times in the space of an hour. Now it really pisses me off when I hear her say it since he pointed it out (thanks for that, fella o' mine!).

Also, if you ask my mum what she thinks of something she's eating (say, when at a restaurant rather than normal home dinner times), it's always 'tasty'. AAARRRGGGGH!! I have no rational reason for my dislike of this word. Do you like it or not? I don't need to know that your taste buds currently function normally.

Teachers
I used to have a teacher who said `on that score' repeatedly.

my mate does that
if he's talking about something serious. He said y'know three times in succession at one point

I thought 'tasty' meant 'tastes nice'.

It does
I did say I had no rational reason for my dislike. The way my mum says it is probably the reason rather than the meaning of the word itself.
