Hahahaha, isn't our society plagued with people of differing personalities and beliefs of all things. Even Body Modification.
Look man, Body Modificiation isn't about being a poseur or getting a fake ring or not. It's that choice to change your look, not everybody likes piercings, tattoos or holes in their ears. It doesn't change you into a bad evil grim person whatsoever, neither will it make you a better peson. Although I do feel like it absolved some problems about insecurity for me. I don't feel the need to 'be' cool.
But wearing a fake lip ring? IMO, it's definitely poseur man. I'm sorry guys, I just think if you wanna do something that badly to get the fake done, then you should really just do the real thing. You know why you shouldn't get a fake lip ring? Because the whole structure of the ring is meant to keep the piercing 'locked'. If you pierce it and put on the lip ring like I did, you will understand what I mean. Being 'locked' in with the constant pain. It's a whole new experience(together with all other piercings) that can never be defined or felt in any other way.
Unlike the normal stud, where the piercing is safe from piercing jewellery rubbing too much on the piercing itself. The ring keeps the piercing in constant motion with the ring. Healing is a bitch, swelling on and off. Your piercing will probably migrate a whole lot if you don't get a ring with the right size. Mine moved a whole centimeter forward.
Best part, getting punched in the mouth with the lip ring on.
