The time of the month when a woman leaks reddish liquid from her vagina. Also known as a "period" or fork.
When a woman possesses clint syndrome she can be very moody and disliked. Be warned.

"Dude... Carol totally has clint syndrome right now. Wait, does that mean we don't have to use protection?!"

"Dude, you're gross."
