<human>: My friend has been collecting his own semen in a fridge for months. He claimed he ejaculated into it via masturbatory methods every night. It was a jug about 1 liter in volume, and it was nearly full.

He showed me this jug because I doubted his claim that he had accomplished such a ridiculous feat. He removed the jug from his fridge and I was astounded, for it was a jug of semen. 

He then took off the lid and smelled the contents. He then held the jar high, against the light on the ceiling, and examined it. I was revolted and jumped up sharply, accidentally striking his arms, knocking the jug, in such a way that the jug spilled about half of its contents into my hair, over my head. 

I was absolutely disgusted. I was essentially drenched in semen. My friend is mad at ME, because I "wasted" half of his "collection".  He was almost crying. Seriously. 

I know I was the one who knocked the jug, but I feel he is in the wrong here. Yet he is claiming I am in the wrong. Who is right?

Can you provide a brief overview of the text?
<bot>: Accidentally knocked a half a jar of semen over on my head, and my friend (the semen owner) is angry. Who is right?*
