mental jukebox

Guy 1:Why the hell was Rick Astley just playing in my head? I haven't heard any of his songs for ages! I had Slayer playing before that! Wtf!?

Mental midget 

You see a movie about a serial killer who thinks he's ugly or disfigured, but never a movie about a guy who's not short, but is convinced he's a midget. A guy with a napoleon complex that shouldn't be there.

The yellow dragon was a mental midget who preyed on tall people even though he wasn't short. He also was convinced he was a coward.

mental midget 

Your average dumbass who still uses "faggotry" and "autism" to describe things they hate. Clearly stuck in the past and narrow-minded to new ideas and concepts, even to old ones that work.

Nikolai shows his mental midget behavior as he shows off his obsession with Pokemon, giving shit to some teenager for making their own fan made designs. Clearly having a shit fit over this.
