A Mirella
A Mirella is a girl who will do anything for her friends, even if it means burning your house down.
She helped my friend move, and in the process, she set my house on fire just to prove a point.
She said, 'I'm your friend,' and then she borrowed my car and crashed it into a tree.
She saved my friend's life, and then she proceeded to make me do 100 sit-ups just for fun.
