This likely has a lot of deep personal meaning behind it. I won't even attempt to guess, hence the simple title. The tattoo looks pretty cool regardless if you understand it or not I think.
Again, I could be way off here. But I thought Demon ripper sounded a whole lot cooler than the possibility of it being say, 'Old dude wearing red contacts needing a manicure'.
There are some important questions to ask before getting a tattoo:
Have I wanted this for more than five minutes?
Am I, at this particular instant in sidereal time, drunk off my face?
Do the tattoo artist's past works resemble an art class for crash-helmet testers?
I meet the love of my life. I romance them for months, reaching a point where we can communicate our very deepest emotions and feel that we almost share souls (awwww). At this point, can I see myself naked and explaining this tattoo?
