I was about to suggest "Intestinal Seepage" but ,after a Google search, it turns out that that's the partial name of a Guttural Secrete song.
I always thought "Butterfly Knife" would be a good name for a band. I think it would be some sort of experimental/ progressive band with an emphasis on duality (the "Butterfly" part representing peace, the "Knife" part representing violence). Maybe it could feature Beauty and The Beast vocals or something. I know this whole idea sounds pretty retarded and gay but I can't really explain it very well.
I also think that "Carrion Banquet", "Carrion Feast", "Cadaver Banquet" or "Cadaver Feast" would make good names for a blackened death metal band.
