My strange stone

A smooth white and black stone
With a greyish tone
I found it on the road
In its humble abode

As I took the stone I think It was disturbed that
I suppose it wanted to stay curbed
Every time I use the object
Things, you could say, weren't that perfect

I was listening to music on my phone
While I was holding the stone
When all the audio out
And let out a sound which sounded like a pigs snout

It did many satanic things from that
It even tried to kill my cat
So I just threw it away
And it'll never come back to me any day
