I knew about the derivation of Pokémon, but the other was new to me. (I am now enlightened, thank you.) Given the numerous jokes within the episode about small penises, I think it’s safe to say this was very intentional.

@Elric of Melnipony  
chinpoko = small penis [chin=penis, poko=small]  
poké = pocket  
mon = monster
 
Pokémon= pocket monster  
Chinpokomon=small penis monster
 
Probably meant as a parody of American obsessed with Japanese culture without really understanding it.

@thps48  
It’s my understanding that Trey Parker is fluent in Japanese, yes.  
Why, what does it mean in this context?

@thps48  
I kinda think that was the whole point.

They knew what chin meant when they made that episode, right? XD

Gerald: You see, son, fads come and go. And this “Equestria Girls” is obviously nothing more than a fad. You don’t have to be a part of it. In fact, you can make an even stronger statement by saying to your peers, “I’m not going to be a part of this fad, because I’m an individual.” Do you understand?  
Kyle: Yes. Yes, I do, Dad. Now let me tell you how it works in the real world. In the real world, I can either get a Adagio Dazzle Rainbow Rocks doll, or I can be the only kid without one, which singles me out, and causes the other kids to make fun of me and kick my ass.  
Gerald: Hmm. Good point; here’s $20. On second thought, here’s $40 pick up one for your brother too.
