swag is no life style ...
The term "swag" has branched out to multiple meanings. Clothing style can be swag, an aura/presence can be swag, and even other inanimate objects can be considered "swag." Consider the term "swag" as a replacement for "cool," but with a little more oomph.
Its when you shit your pants and noone knows about it.
Moreover, if you ever attend nerd conventions, they usually have hand-outs that are called "swag bags." It's just a bag with neat promotional items in it such as flyers, pins, stickers, comics, etc. AKA, a bag of "cool" shit.
that pritty much answers yr query
95% of teenagers have switched over to RAP/POP. If your one of the 10% that still listens to REAL MUSIC copy and paste this to your sig.
Swag is an old term that used to be the free promo merchandise you got from concerts, magazines etc. Like, old Playstation magazines would give out "free swag" in their magazines in the form of posters, game demo CDs, etc. It's been appropriated by hip-hop culture to mean fancy clothes, acting like a douchebag, etc.
Swagger is the way you carry yourself, your confidence, etc. "That dude's got swagger", ie he's really confident and probably has lots of sex with pretty ladies.
