You can win me and lose me but never buy me
You can not eat me and never want to part with me
I can make you cry or bring you joy
I am not a machine and definitely not a toy
You keep me but i am not forever just yours

I am made of different materials and am at many events
If your lucky and fight hard I might be yours
