Why not have a chorus of them? Probably would sound better.
Haha, funny. Oh wait, I think you're serious. No, no a grindcore song doesn't have a loving chorus. A grindcore song is usually about 15 seconds - a minute or a bit more, is nothing but blasting, and can either just disgust you, or give you something to listen to while you forget stuff up.
If you meant my songs; No, once again, this type of music doesn't have choruses.
I had a feeling none of you would know how to appreciate grind/slam/core (JD as an exception).
