Teens throwing Tattoo parties

Many teens nowadays are throwing tattoo parties. There are teens over the whole entire world that are throwing tattos parties. Such as my friend had a tatto party. I'm kinda happy i didn't go to the party because I didn't know if the guy that was throwing the tatto party had clean needles. I don't think that teens throwing tattoo party's because you never know if they use the same needles or if they dispose old needles.
