A Priscilla
A Priscilla is your best friend forever, and if she doesn't like you, she'll beat you up and then still be your best friend. She's tough, never backs down, and if someone roasts her, she'll roast them back twice as hard. She's the kind of person who will fight for you, even if you're an idiot.
Priscilla: 'You called me a fool? I'm going to make you eat my words.'
Priscilla tripped in front of the whole class, then walked back to her seat like nothing happened.
Priscilla told me she'd rather die than let me fail, and I believed her.
