delete() starts a delete sql statement. You can add .where() to narrow down what you are deleting. It's a class method. 

class User(Model):
    username = CharField()
    join_date = DateTimeField(default=datetime.datetime.now)
    is_admin = BooleanField()


User.delete() # would delete all users in the database

delete_instance() is a instance method, that will delete the database row represented by an instance of a Model subclass.

me = User.create(username="myers") # create a new user with my username
me.delete_instance() # delete me from the database
