Russian Interference
Russian Interference is term for when a man, (usually a Russian), tries to sabotage your plans to have sex with your girlfriend or boyfriend. This may be either through sabotaging you indirectly and in ways you don't realise until it's too late, or a more direct method like opening your bedroom door and coming in naked while you are in the middle of making love.
"My roommate spilled wine on me, I swear he did it on purpose, I had to change my top and when I came back downstairs my boyfriend was nowhere to be seen. Talk about Russian Interference!"
"I arranged a first date with this hot guy, but when I got there, my ex, was sitting next to him. Apparently he just happened to be there and they had just hit it off at the bar? I swear he's hacking my phone dating apps. Fucking Russian Interference right?"
