A man who eats pussy when his girl is on her menstrual cycle.In other variations, the man fucks the bloody cunt, then the girl sucks his cock clean. Named because of the blackcurrant drink Ribena.
Harry doesn't miss out if his girl is on her period, and neither does she. He happily admits he is "A bit of a Ribena Boy!"
