ImpossaBitch

1. A seemingly impossible boss fight that standard tactics don't work on, turning the fight into a real son-of-a-bitch.

2. Someone that, no matter how fly or pimp you be, denies all advances and shuts down all comers; which, in response, makes you continue to try and refuse to give up on.

1. I'm new to bullet hells, so Sans was proving to be an ImpossaBitch.

2. I made her friends laugh, same taste in film & music and this ImpossaBitch still won't accept a drink.
