sock in a flip flop 

Another way of describing the phenomenon that is the Camel Toe, an American Tradition and Classic. When a women wears a pair of pants or shorts that shows her beefy pussy flaps actively swallowing the seam of her pants. It looks like when unstlyish dorks wear socks with their flip flop sandals.

"Damn Joe, Sally's shorts look like she's wearing a Sock In A Flip Flop!!"
"You're right Jim, I like that shit!"
