A ring of menstrual blood placed around the forehead of a female during, before or after engaging in sexual intercourse while she is on the rag.
My girl is a such a little devil in bed that I decided to make her a saint by giving her a bloody halo!!!

When you fuck a girl on her period and then take the blood off your dick and draw a halo around her forehead like Jesus. Similar to the dirty sanchez.
My girl was trying to act like a martyr so I gave her a bloody halo.
