Male Executive Creative Director to female Senior Art Director

Our Male ECD: "He's totally fucking her." (talking about our CEO and a junior level female)
Me: "Um, I don't think so. So for this concept, we..." (trying to get back to presenting work)
Male ECD: "No, they're totally fucking. She's always flirting with him."
Me: (clearly uncomfortable) "I don't think either one of them would do that."
Male Copywriter: "Yeah, they're always flirting."
Me: "She's just being nice. That's not flirting. But they're definitely not hooking up."
Male ECD: "Yeah, okay. They're totally fucking though."
