Yes, yes I have actually. I have 4 tattoos. Crypt Keeper on my left arm, undead jester on my right, Resident evil sorta spider on my chest, and the name of someone very special to me on my heart written in "a perfect circle" letters. Also, piercings. Ear, both of my nipples, and my tongue.
How it did happen? Well, body art has been very appealing to me since an early age. It all started back when this wrestling show "WCW" was on air, and there was this one wrestler called "Vampiro". He had tons of awesome tatts, and well that was it for me, I wanted to be like that guy haha. Also, I guess its an addiction as well. Once you get one done, you want more and more. Thats how it is for me at least.
Why?
Well, why not? I spent more money on booze, food, games, etc than I did on ink/piercings. Besides, I wanted something that I can be proud of having and something that will stay with me forever.
