Male Executive Account Director & Senior PM to Female Junior Strategist 

I had been resting my head on my hand during a meeting, which left some sort of temporary red mark on my neck. While walking back to my desk, two high-up account guys loudly said "Is that a hickey??" in front my all my co-workers, pointing and laughing. I couldn't even give them a "No, it's not", because their jeering, pointing, and general 2nd-grade-boy behavior continued until they walked away, into their meeting with our CEO.
