DLST is an acronym for "Dirty Little Slut Tattoo". This specifically refers to a tattoo found on the lower back of a female. The tattoo generally consists of a celestial object or a decorative horizontal pattern on the external lumbar area, slightly above the sacrum. Such a tattoo obviously has no use to the owner and can only be enjoyed by someone else from behind.
" Did you see the new DLST that Britney Spears is sporting? What a white trash whore!"
"That chick most certainly takes it in the ass... Check out that DLST."
