You are wrong.  Just because you play golf does not make you a golfer.  It makes you a teacher who once a month plays golf.  Participating in an activity does not make you.  I have put a new faucet in before.  I am not a plumber.  I pulled my own tooth once.  That does not make me a dentist.  Walk up to any pro golfer or competing amatuer golfer and tell them you are a golfer because you play once a month and they would think you are nuts.  Anyway, you and Goodrum are thinking alike.  That right there should be a warning you might be wrong on this.  
So, if I fart 10 x a night and my wife farts only once, we both are farters at some point during the night...right? 

LOL, damn , you are missing the point. I am simply making a point about the LITERAL meaning of any descriptive term or action.
For example,  two girls pole dancing ; one a hot 110 lb blonde , the other a 300 lb skank with a mullet and body odor.
BOTH are pole dancers, but only the blonde looks like she is a SEXY pole dancer.
The question really is, when does someone develop enough muscle to be considered an obvious bodybuilder.
FYI, I have not played any Golf in over 10 yrs, but if I go out a play this weekend ( I won't) I would be a GOLFER even if I sucked.
