FCD, or Fish Cunt Disease, is a medical condition in which a woman's vagina smells like the sea. Women with FCD should be approached with extreme caution, as their stench has been known to cause nausea, irritability and blindness. While easily treated, FCD is an incredibly common disorder among females who neglect personal hygiene, and while there is no official cure, symptoms can be managed by a regiment of frequent showers, followed by a deep dicking.
Bill: Hey, did you finally bang Shelly last night?
Steve: Nah man, we were making out, and shit was getting hot, but as soon as her pants came off the entire room stunk like the Pacific Ocean. Bitch has a bad case of FCD.
