This happens when a girl has a large amount of pubic hair that resembles a temperate rainforest along with an excess amount of crabs similar to the deadliest catch. She shakes them out over random foods such as fries or eggs with a salt shaker like effect. She can also sit on a margarita glass to salt the rim.
A mudded pussy is preferable to achieve the best results.
"Bro, that nasty ass whorebag salted my fries with her salt shaker pussy."
"My fiances best feature is definately her salt shaker pussy."
