Beautiful/handsome/awesome/cool/interesting/chill, all in one. Gender neutral compliment, but can also be someone's demeanor. It can also be used as a nickname!
(I know the word from a Yagami Yato audio so this is all from context, and I don't know if it has any other origin)
You're beautiful, handsome, all at once - beautycool, even!
Trust me, not everyone is beautycool when it comes to that.
A mixture of hard rock and metalcore, played exclusively by women. Bands generally have two guitarists, a bassist and double kick drums for the instrumentals. Many bands use more than one singer, one generally for more melodic lines and the other, who carries many of the vocal burdens and usually "screams."
Gold, Frankincense & Myrrh is the girl-version of metalcore; you could say they’re the best beautycore band I’ve ever heard!
