Bitch (noun): A woman who won’t bang her head against the wall obsessing over someone else’s opinion – be it a man or anyone else in her life. She understands that if someone does not approve of her, it’s just one person’s opinion; therefore, it’s of no real importance. She doesn’t try to live up to anyone else’s standards – only her own. Because of this, she relates to a man very differently.
