The act of having your thinking proved wrong; often characterized by an "oh" said by the person being mentally dominated. You can be mentally dominated by a test that you get a bad grade on or you can mentally dominate someone by winning an argument.
John thinks that there are 31 days in April. Kevin shows him April on the calendar to prove that there are only 30 days in April. John says "Oh." Kevin yells "Mental Domination!!"
