Friday Word Fun

Huh- I guess my theme the past couple days has been "words".
Perhaps a subconcious probing to get back on track with my writing.
Anyhoo - I digress.
Please read the following:

You have got to be freakin' kidding me!  That is awesome!  No way, dude.  That is just crazy!

Now I ask you; how do these words work their way into our everyday, common-speak?

There have been others, of course: "cool", "bees-knees", "foxy".  (please note that at least 2 of the afore mentioned examples were waaaay before my time :)

Really no insight from my end.  Just wondering out loud.
Have a Happy Friday and a great weekend!

Any other words or phrases you think have been overused in our pop-culture over the years?
