I was throwing a party and my friends were bringing their friends. Bernie-a friend of a friend- was constantly hitting on me and saying a host of lewd remarks. I could see my SO steaming, and I discreetly said something along the lines of 'I want to fuck you'. After a quickie, my SO was calm and couldn't care less about Bernie's remarks.

Unfortunately, said SO and I are no longer together, but I'm keeping that trick in my back pocket. I hope it helps any of you ladies out if you're ever in the circumstance.
