a tattoo on the lumbar section of a person. called such for the association of promiscuity and the tattoo's placement especially when intentionally worn exposed through a combination of low-slug bottom/high-cropped top clothing. also used by some as a target during doggy-style intercourse in order to shoot one's load onto it... also referred to as 'putting one through the uprights' as it implies kicking a field goal, only in a sexual connotation :)
