Im' not sure if it's the good place to explain this (I'm new here), but I think I found what exactly マニィコーチン (the japanese version of Manny Coachen) means.
I think it's from an french expresion "ma nicotine" (my nicotine). It remind me about a character from another game called samuraï spirits (samurai shodown), Caffein Nicotine (http://snk.wikia.com/wiki/Nicotine_Caffeine).
In japan, people love to use english or french languages in whatever (and sometimes in inappropriate) situations.
I strongly think it's meant for "ma nicotine" in this case [GK. case n°5].
