Brittlecore 

British screamo, like Bring Me the Horizon.

Hey, did you guys see the brittlecore concert yesterday?

I know, those guys killed it with the screamo version of "London Bridge"

brittnicore 

girl who lives in her own genre. more than hardcore. exciting, spontainious, easy going. lover of whiskey and fun people.

Although she was a nice girl, she wasn't quite brittnicore
