A bloody Russian is when your girlfriend / wife gets sick of your drunk ass & decides to piss in your vodka, adding a touch of period blood. Blame it on the Grenadine & cherries & make him a nice drink.
wife "Hi honey, had a hard day? Let me make you a nice cocktail."
husband "Yeah bitch, make yourself useful and make me a few."
wife "Sure thing sweety. Extra cherries? I call it a bloody Russian"
