Yeah the one on your update is OK...
cheesy and tacky.
OK if they wear a honking big gold chain, then, Yes! Very cocky, full of themselves and super annoying! lol sorry, I just hate it!
But if it's a small chain then it's kind of nice and it gives the guy some style... as long he doesn't have the stereotypical personality of macho/player that some guys usually have who wear gold chains...
Hopefully that makes sense! :)
wearing a gold chain doesn't = cocky personality
but a good percentage of the cocky personalities wear gold chains, so I see where you get the connection, but no, I don't think they are cocky just because they wear one.
