When a woman is on her period, she lets the blood spread everywhere. Then the man takes out his penis, ejaculates onto the menstrual blood, and swirls it around. Thus, creating the candycane effect.
The act of sex in which a male partner sticks a lollipop up the orifice of the female partner repeatedly until an orgasm happens.
Mike: Dude, I was totally candymanning my wife last night.
Eric: Really? What type of lollipop did you use?
Mike: Tootsie Pop. I stuck it in so many times we got to the Tootsie Roll!
Eric: Damn, you must have been at that for a long time then...
