when someone cums in a woman's ass after eating them out on their period and then taking a shallow straw and sucking the cum, shit and blood out of their ass. this can then either be shared (like snowballing) or swallowed on it own. Meant to taste like hamster.
I gave Sarah a dirty bom bom last night. She loved it. She cried while sucking back the tears.
