After you blow your load, inside the vagina during a girl's period, it is the combination of cum and blood clots dangling on the tip of your dick when you pull out.
My girlfriend wanted me hard again after fucking her during shark week. She went to blow me but gagged on the red yo-yo.

Get the red yo-yomug. yo yo effect (n) - the action of a girl or boy from a past realationship toying with your emotions. Sending signals that they want you back and suddenly being very cold to you off and on. Sort of keeping you as a back up if their current realationship or intrest fails
