Swag is a term that refers to a person's sense of style or skills. It is derived from "swagger" and was made popular by hip-hop culture. Swag is usually preceded by a hashtag (#) and used profusely on Twitter, commonly to brag.
Swag. This explanation is taken from a site called Slangit after searching for a while on the web. I get that people can be humurous here, and I enjoy that myself, but there should be at least one entry that's not a joke and that actually refers to the meaning of the word. As a foreigner, this site is a resource for me, so please help by adding helpful entries. Please upvote so others can see.
