It means nothing.
A navel piercing on the left, no meaning, it's just a piercing.
It means they have a piercing in the top of the left ear nothing more nothing less.
That you wanted it there. That's all
It doesn't mean anything. I honestly think that if you have a nose piercing on the left side of your nose it doesn't mean anything. Most guys do but that doesn't mean they are gay.
Where I'm from usually the left lip piercing symbolises being a lesbian but this is not true as it is up to the person who gets the piercing which side they prefer xx
That you decided to get a nipple piercing.
It means you wanted it done. You like it. No piercing means anything specific.
It means that he wanted a lip piercing :)
Having a piercing on the side of your lip :3
OK you mean to say "industrial piercing" this is a straight barbell through the outer ear cartilage in two locations on the ear. Right side left side makes no difference in the grand scheme of things and means nothing.
It would mean the twelve year old has a cartilage piercing, nothing mystical about it, it's just a piercing.
It means it is a piercing that will lead to other piercings.
