Why not just hang a picture on your wall and enjoy that instead, why use the human body as a flawed canvas? Nothing says low intelligence quite like a tattoo. It's for people with no imagination and no concept of foresight.
why is it a flawed canvas? ink will fade on just about any surface over time. a well done tattoo should stay in good condition for 10-15 years, then when it does fade you can have it touched up/refurbished.
i guess you are also one of those pussies that says "just think what it's gonna look like when you're old and your skin is all wrinkled"....well you're gonna like sht then anyway without tattoos.
if you think you can get a read on someone's intelligence because they have tattoos, then you've obviously led a very sheltered life and are probably a bit of a fag by all accounts.
i'm not talking about shty generic tribal bands or clowns with tats all over their face but good quality artwork.
