A woman so very dedicated to her work or studies that she begins to have wrinkles on her mouth, reminiscent of a catfish. Can normally be seen in law school, but is full-fledged visible in the legal practice.
A person who follows another person around. They suck up to that person because the person's social standing is much higher than the catfish's. The catfish is often fat, unathletic, skinny with glasses, or just annoying to everyone around them.
