Reason why I want a 420 Tattoo

Every tattoo of mine has a meaning, so far I have 4 pieces, my first tat was 10 stars going down my right side, symbolizing me and my 9 siblings that basically got separated in the system, second one is a music note symbolizing my passion for music is on my left shoulder and the third one is a dream catcher symbolizing my childhood on my left upper arm, my 4th is the word amazing and Aquarius sign. I feel getting a 420 Nurse tattoo will symbolize my loyalty to the community and I also feel it is a perfect way to symbolize me threw self expression i would like my tattoo to be places either on my left waist line or on my left butt cheek or on my back lol
