Recepy for Crusty Crabs:

- Have consensual intercourse with a Female that has Crabs
- Jizz (Shout your sperm)on the vagina of this female. *
- Let it rest for about a week so the Jizz has some time to set in so it changes to a Crusty substance.
- Now Rub the Cum Crust of the vagina into a bag.

Voila, you now have Crusty Crabs!

*It is okay to use the sperm of someone else if you do not have any available.
I really felt like grabbing some Chicken McNuggets at the local McDo but i figured i had a nice bag of Low Cal Crusty Crabs at home.
