A screamer is basically a random video that makes you focus on the screen more, and usually makes you turn up the volume. Then, the scream comes, and it's really loud, along with a scary picture, usually.
Of course, you probably knew that, considering that link is probably one.
Anyways, getting back on topic. Xeano gets a 6.5 because it's okay, but I think you can add more stuff to it.
