Traditionally tattoos were messages. Historically they indicated rank, or some ritual, some passage of a trial. They were meant to commemorate a significant event or a significant stage in life. Tattoos were read by others and understood in terms of maturity, warrior status, and rank in the tribe. And it is the same today.
Anyone stupid enough to get a face tattoo, a neck tattoo, or finger tattoos is advertising openly, "I am a criminal. I am a drug addict. I will never be employed." They are telling everyone about themselves without ever saying a word. Essentially they are telling everyone, "I am a loser, and will be a loser to my death."
