When a girl sends a nude picture of herself and it appears she has a thong. After close examination though, you can clearly see she doesnt. It's just a shadow that her fat makes.
"Dude I was so dissapointed when she was wearing a thong in the picture" "bro, she isnt wearing a thong, it's a shadow thong!" "eewww!"
