Your example scenario made me LOL, so I voted 'funny'. XD But to be honest, I think it's kind of creepy.
If there's one aspect of romance I'll never truly understand, it's how being possessive is viewed as flattery. =/ And thus, the extremes of possessiveness, all the way on down to the yandere end of the spectrum, are viewed as 'hot' and 'sexy'.
Like, personally, I wouldn't want someone to be offended by the fact that another human being might look at me or talk to me or, dare I say it, think I'm pretty. Like, chill; damn...
