Any time some teenager shouts "SWAG!" "SWOOP!" or "WHOOP," please don't be annoyed or alarmed. For they may have an involuntary condition that has only recently been diagnosed: Swag Syndrome.
Although such verbal emissions may sound like a kid is bragging or expressing themselves in the most annoying way possible, it's important to have sympathy so that a cure may be found. One doctor may be close to finding a cure for the involuntary shouting once thought to be in reaction to "objects of exceptional baller-ness"; however, it seems that the affliction goes much deeper. Turns out it's just the weirdest form out Tourette Syndrome ever.
Please, if you meet a victim of Swag Syndrome, have a heart. They may only be a support group away from help.
