Hahahaha !! When Matt and Trey did the episode they asked their Japanese friend for help. Of course,it doesn't make much sense in English but it's just basically every curse word in the Japanese language converted into a song..
Here is the translation.
Wonderful penis thing
There are hairs at balls
That's sound of Monkey-like C*nt
No! Ninjas are here!
Hey hey let's! Lets fight!
This is important. Protect my balls!
I'm badass. So let's fighting
Let's fighting love!
Let's fighting love!
This song is a bit stupid
This doesn't make sense.
English is all f*cked up
It's okay--we do it all the time!
