When a girl or guy looks really good in their thumbnail picture on facebook, but when you open their page and see the blown up version it is less than satisfactory.
Dustin: Aww man that girl looks hot, check out her page!
(clicks open page)
Dustin: Dang, I thought she looked really good...
Gary: Yeah man, she's got thumbnail swag.
