I can throw in my opinion here as well. As GB and others have adviced you, getting a tattoo of Kurt's face on your body is a terrible, terrible idea. Getting faces right is hard enough. Getting them to look right on skin which sorta moves around is even harder. Plus, you're not gonna love it a few years down the line. Those of us well past our teens know that. I used to listen to punk and skate a lot in my teens. If I'd ever gotten a Johnny Rotten tattoo then, I so would have regretted it today.
edit :
By the way, I do know people (notice how that's plural) with tattoos they regret ever getting so it does happen
edit again :
Tattoos have had their renaissance with Miami Ink and all that s
hit. They've been cool for years now. Isn't it about time they became uncool again?
