Means godly swag. Having a very confident demeanor in every pursuit in life yet being humble at the same time. Speaks eloquently and inspires everyone around him. This level of swag is almost unheard of and is so powerful that only the most beautiful of women would dare approach someone with Heffler Swag.
Me: Dude look at that guy, he's getting all of the girls!
Friend: Ya man, his Heffler Swag is on fire!
