swag - apperance ,style ,or the way he or she presents them selves.
(Example: He got a killa swag)

An overused buzz word is one that has peaked in popularity
(typically this decline occurs after overuse by mass amounts of people).
Unfortunately there is very little that can be done after a buzz word has peaked.
The only suitable thing to do is find a suitable alternative and wait a minimum
of five years before uttering said word again.

How do you know if it has peaked?
When someone your parents age uses the word in casual conversation
...yes...my Mom said swag today signaling the end of times.
