A type of sperm secreted by the vagina of a wolf named Seasonal, who resides peacefully on Wolf-Haven.com with her mate, Sheri, her pack, Shimmer, and her Chatbox friends, AKA The Douchebags. Rainbowsperm is dangerous, and when it comes in contact with another penis/vagina/mangina/pengina, a baby with moar rainbowsperm will be created (an example would be Sealiah).
Dylan is only awesome because he suffered a rainbowsperm attack.
