eh, i've seen some awesome prison tattoos. a lot of the 'new school' influence is from the prisons out in california. i'm not suggesting a 15 year old start experimenting on himself, but there is quite a huge difference between some kid makin up an art form and the vast tattooin population in our prison system.
i used to have one on my hand, stupidest shit i ever done. it was with a mecanical pencil and it was a heart, it lasted for like a year. dont do it.
DON'T DO IT!! it's a mad bad idea. whatever you do will fade like someone above said or it will scar and you probably won't want whatever you do. yeah, it seems like the cool thing to do, but you'll be cooler when you're 18 and have a sweet ass professional tattoo and all your "cool" friends have big blotches of black on them. just wait. and please, never cut yourself in any pattern for any reason. if you want scarification you should get that done professionally as well.
Dont do it dont do it dont do it dont do it!!!!!!! Trust me it will make you look like a drop kick. Ive seen them. Just wait, get it done somewhere professional, then it will look fantastic. WHAT IS THAT SUPPOSED TO MEAN???
