Crab mentality There is a term " crab mentality" in psychology. It describes a way of thinking best described by the phrase “if I can’t have it, neither can you.” The metaphor refers to a pot of crabs. Individually, the crabs could easily escape from the pot, but instead, they grab at each other in a useless “king of the hill” competition which prevents any from escaping and ensures their collective demise. The analogy in human behavior is that members of a group will attempt to “pull down” (negate or diminish the importance of) any member who achieves success beyond the others, out of envy, conspiracy or competitive feelings. Don't be crabs. Don't let them grab you.
