Trust me, the slightest and strangest things can be considered sexual harassment to some people. It's considered sexual harassment even if it wasn't intended or directed toward anyone or even known by the offender (at least in Ohio). I've never made sexually suggestive comments toward people, and yet some people seemed to feel it was implied. This is the sort of thing that cost me jobs in the past.
And so I've been figuring out ways to get back at women for being so uptight. I assumed I can use their flirty advancements to get them to taste their own medicine.
Oh, and the definition of flirt is "to make playfully romantic or sexual overtones." Yes, that could qualify as sexual harassment -- it is very risky behavior, indeed.
