A sexual act in which while a girl is on her period, her or her partner proceed to rub her period blood and menstruations on her stomach, and then her partner will give her a raspberry on her abdomen (like blowing on her stomach to make the fart noise) whilst it is covered in the bitch's blood.
"Aw Jeff lubed me up in my own period blood last night on my stomach and gave me the best sour raspberry"
"After sucking some dick and farting some cum, Jeff decided to give me the best sour raspberry this millennium has ever seen"
