A musically watered down style of metal that's meant to be as inoffensive and possible and appeal to the widest demographic possible. Also commonly overlaps with octanecore.
"Old school" butt metal is basically mediocre groove metal/NWOAHM, it can also surprisingly overlap with (melodic) extreme metal, for example FFDP, Damageplan and the album Trust No One by DevilDriver
"New school" butt metal is typically inoffensive, easily digestible metalcore, for example Bad Omens, I Prevail, Spiritbox, new Of Mice & Men, new Architects and most legacy metalcore acts trying to be relevant nowadays (Atreyu)
