Although I think that idea is crossing the borderline into psycho bitch overly-obsessive batshit crazy, whatever lyrics you decide to have tatted, make sure to have whatever song you have the line from next to it, hence:
Don't you come near me cuz the Devil's sittin next to me, I drink my drink and smoke my weed and pop my ecstasy - Trapped In A Psycho's Body
Or something along those lines.
Can you imagine that on someone's back?? I'd never talk to that person again.
