Definitions
The phrase 'has a crab mentality' refers to a way of thinking where a person tries to hinder the progress or success of others out of jealousy, envy, or competitiveness. It comes from the idea that crabs in a bucket will pull each other down, preventing any from escaping, rather than allowing one to succeed.
