Carmen,
My girlfriend and I had a situation at work where people were trying to sabotage us. There was a promotion coming up and as people vied for the new job many were using dirty tactics.
My girlfriend and I would be sitting amongst them, knowing exactly what they were doing. We would be working and talking across the aisle. Our code word was Haman. We'd say, "Oh, he's a Haman, or she's a Haman," they hadn't a clue what we were talking about. We got a lot of giggles over that.
