Just do it the right way when you are stretching your ears because I've talked to someone that ripped their earlobe from trying to stick in size 0's right off the bat. Do the process right with smaller size tapers first and from their decide how big you want to go. Just remember if you go past 0 there is more of a chance that your holes will not close back up and you might have to get them surgically closed.
Oh! And cleaning them is a daily routine, I remember when I didn't clean mines they smelt like cheese haha.
Hope this helped your decision! :)
It's neither a good nor a bad idea. If you like them, and you want them, then do it. Don't let people tell you otherwise. Do your research, and decide from that.
Do it properly, be smart about it, and understand that, after a certain point, there is no going back.
Just know that if you make them too big and one day you decide you don't want them any more its going to take time to shrink and sometimes it doesn't shrink all the way. So do a decent size if you decide to do it.
Considering you don't even know the correct terminology, I'd say you're WAY too young for them and you should get off the Internet and go play with your Barbie dolls.
DONT DO IT DONT DO IT
BAD! BAD BAD BAD IDEA!
If you get small ones it shouldn't be that bad but like get them once and thats it for a few reasons.
1. Once your ear is all stretched out and you don't want them anymore you're left with stretched out flappy earlobes which will cost a lot to fix.
2. Theres a thing apparently where random people put a padlock in it, lock it, then run away.
3. They will hurt, a lot.
4. People will criticize you thinking you're a idiot or something other that I can't say on here.
5. Like number one, once you have them... you have them, forever (A really long time!) unless you get reconstructive surgery because I don't think you'll want them when you're 60.
Overall, my opinion, bad idea.
Substitute for them: Get piercings that look like spacers, its a thing.
