When you give a girl face when she is on her period
"Baby come here and give me a Bloody Rainbow"
When you nut inside of a girl while shes on her period.
Babe, look! We made a Bloody Rainbow!
It is when two gay guys kiss each other but they have period blood on their lips
Omg they are Bloody Rainbow Kissing with my blood
when you make a girl bend over like a bridge and eat her pussy whiles she on her period
