This is usually announced or thought of after seeing a girl who is distractingly attractive. The act of explaining you like the looks of a girl enough to masturbate too.
See, she's hot dude I'm going to ask her out.

Yea I'm masturbating in my head to her.

I fucking hate you.

I'm still masturbating in my head to her. Still not done, not done, Alright I'm done. I'm going to go make a sandwich. Good Mental Masturbation. Actually, you want to go to Chipotle?

The act of engaging in impractical/nonproductive mental exercise/thinkings/writings through which a practitioner only comforts oneself mentally. Such acts don't lead to any constructive results what so ever in the real world; some might even imagine oneself being transformed into superman, or simply the opposite sex, etc.
In short, it's just bs/crap.
Example1:
Guy1: My boyfriend went abroad so I can take over all his stuff and start anew.
Guy2: Dude, you're the same person all along; stop that mental masturbation and get the hell out of my sight.

Example2:
Guy1: I think biological evolution is bull, but mankind can evolve to become God.
Guy2: Dude, you're all fucked up; you can go on with your mental masturbation, but stop bordering me anymore.

The term coined by the promising new hope of psychology. Christopher, the surefire future of psychological theory, defines this term as the psychosexual pleasure that one receives from playing mind games with others. Christopher is a godsend to psychology.
I am, however, at the point in my life where I do not need to subject myself to the “mental masturbation” which envelopes your games.
