Fr00tal
Describes someone who enjoys listening to death metal, metal, metalcore, deathcore, etc. and sports band t-shirts with more than 3 vibrant colors strewn across the otherwise brutal artwork, making the individual look like a bowl of Froot Loops. It's a play on the words "fruity" and "brutal."
I saw a kid walking in the mall with a shirt that looked like a unicorn had vomited all over it. As I got closer, I realized that it had a werewolf tearing apart a robed man with The Black Dahlia Murder in bright pink at the bottom. It was pretty fr00tal.
