zero to rapey 

When you meet a stranger and you're not hitting on him but socializing and as the night progresses he goes from no sexual intentions towards you to a slightly scary creeper. This can be true to for men meeting women but that's more of a zero to clingy scenerio.

I meet this guy at the hotel bar on a business trip, he went from zero to rapey in three drinks flat.
