You should tat whatever you want on your body wherever you want. yes the whole japanese lettering, kanji, gracie triangle is a bit played but so what? Do you really care what some douche bag on the internet thinks?
For me I have two tats, both have meaning to me. 4 years of latin in HS and 4 years of latin in college, plus 2 years of random latin lit classes in grad school. Guess what, I have a latin phrase tat. 5 years in the marines, 32 months of combat pay, I have a generic marine meat tags. Do I care that both are a bit cheesy, maybe, but they still are part of who I am. No regrets.
Very few people would have a problem with your tattoos. You obviously know what your tattoo means, I'm simply saying, if you can't read what it says, don't get it.
