Nahh my late response was as early as that one guy who always shows up to the party when you're not done setting up yet
Swag is the way you carry yourself, but it includes other things. Basically, it encompasses your walk and personality. If youre cocky, confident, and you've got the credentials to back it up (a few experiences of taking charge or bsing something), then you've got swag. But 13 year olds? No swag.
