mental suicide 

The act of doing too many intellectual/ thinking required activities in a short period of time. This causes an immense amount of strain on the mind, instead of dealing with the problems at hand the mind committs suicide by shuting off and leaving the victim incapable of completing a thought.

Juan: "Omg I heard your taking 3 SAT subject tests tomorrow."

Joe: "Yea. Calculus, Chemistry, and French."

Juan: "Dude, that's like committing mental suicide. You're brain is gonna be fried"

mental diahoreao 

The sensation of an uncontrollable string of thoughts that can go off on tangents at any time, usually resulting in the sufferer becoming stressed and restless.

An example of a string of mental diahoreao; "Edan cheese tastes weird, what is that red stuff around it, it tastes awful, awful like that vinegar I drank, i wonder what kind it was, i need to sleep though, I think i was spanish, ah bull fighting I'd hate to be a bull, although if i were put out to stud I'd be alright, studs in people's head look weird sometimes, anyway I must sleep now. although didn't that guy i saw at the bus stop have a stud, it looked cool, i wonder what he was eating, oh man I could eat some KFC, yeah a big bucket, like a victorian prostitute eating KFC in the night, i really need to sleep now, maybe if i just don't think," 2 minutes later "although I'd hate to get the clap.."

mental loner

Unlike an actual loner, a mental loner has friends to hang out with, but thinks that all his/her friends are worthless idiots and feel alone.

This girl is a stereotypical weeaboo, and while she hangs out with friends, none of them ever watched a single anime, so she considers herself a mental loner.

Mental Domination 

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!!"
