I lost a Gfriend once in a similar situation.
We had a scary movie night, and rented the Exorcist movie series. So, we watched it, and she was all nuzzled into my chest all scared and shit...
So, I thought I would pull a funny....
We went to bed after the movies and she was creeped out... so I said "Everything is ok... Here, check this out..." and I proceeded to make my head spin 720 degrees, and I puked all over her.
She got pissed, and took off. I haven't seen her since.
