Mental Horsepower

When you personally have made a repair to a machine and feel that it works better just because you worked on it. Even if the part of the machine you worked on would not make it work any better.

Jim: "I replaced the heater core in my car, now it seems faster..."
Sam: "I've heard of that before."
Jim: "Seems to run smoother too!?"
Sam: "That's Mental Horsepower!"

Mental E-tardation

The physical state of the brain following consumption of ecstasy in which attempts at complex neural processes result solely in the self-realization of the tremendous mental toll ecstasy has on your basic evaluative skills.

The day after the rave my friend was suffering from severe Mental E-tardation and tried to put a hot pocket in the blender.

mental whack picture

a mental snapshot that a man takes of a woman or certain parts of a woman he sees in public so that he can jerk off to the image later.

It would have been too obvious for Dusty to take an actual photo of the hot woman he saw with his cell phone, so he settled for a mental whack picture.
