Logically negates itself
A self-contradiction is a statement or position that contradicts itself, making it logically impossible to be true.
If someone claims to be a strict vegetarian while eating a hamburger, that's a self-contradiction.
The term also describes the quality of being self-contradictory: The witness's testimony was full of self-contradiction.
Something self-contradictory contains elements that cannot both be true at the same time.
