The pound sign will appear as # in Latin script and indicates that what follows is should be read as a number in some series.

May also be referred to as a hash especially in computing circles or outside of North America or number sign.

A tattoo on the lower back of a female. Generally some kind of tribal tatt, seen on the wall of a tattoo shop, or a butterfly, dolphin, or sun burst. Usually seen just above the thong line, to draw attention to it.
