The term tramp stamp has a derogatory connotation and should not be considered relevant when deciding to get body art. Getting a tattoo is a personal decision that has nothing to do with such a label. Another popular trend for women is to get sexy foot and ankle tattoos. There has not been any negative labeling or backlash for these locations or even the more sexually explicit areas of breasts and genitalia, although these are less common locations for tattoos - they nonetheless do invoke a more sexual connotation - and yet the lower back has received more attention.
A tramp stamp is a tattoo on the lower back of a woman. It is usually small but can be any size the wearer chooses. All kinds of women choose this kind of tattoo because they like it. There is no one particular kind of personality that admires a tramp stamp.
Tramp stamps can be intricate designs or they can be super simple. A very simple design would be a heart or a teardrop. Something more intricate could be intertwined flowers or an animal like a bee or a bird. The lower back is the perfect area for horizontal designs.
