I don't know of it'd the worst, but one time I was chatting to this girl for a couple weeks. Agree to meet up with her, turns out she was using me to get to a mate, I find this out as o fond them cuddling when I go round said mates house. My mates brother was builder, and had bags of concrete outside, so I grabbed one put a slit through it and emptied the whole lot on her car.
