difference: trainor vs trainer

[Hitch]

Please tell me the difference between trainor and trainer. Are there specific contexts that provide clues for its use. :?:

I am not a teacher, but I do not think that trainor is a word in the English language.

UrbanDictionary have a meaning for it, but it's the first time I have come across the word:
Urban Dictionary: Trainor

Also, this could be a private joke based on someone's name, like many entries.

This is definitely someone's private joke.

That's one of the problems, or possibly joys, of this site. ;-)
