Sort of

This has become the preferred "verbal seasoning" of those seeking to appear hip.   It is a completely empty phrase, no more informing than "um" or "ya' know".  Even my beloved Coen brothers are seriously afflicted with this affectation.  For an example:

http://thehollywoodinterview.blogspot.com/2008/02/coen-brothers-hollywood-interview.html

In one page, they use "sort of" 14 times.  In no case did it add any meaning whatsoever.  Remove it everywhere it appears, you have the same interview.

It's sort of annoying.
