A sleazy, cheazy bar or club where the only reason anyone goes there is to pick up. If you're not there for this reason then you'll have a terrible night being unwantingly groped and hit-on. Girl's and guy's grind amongst one another to see who they will fuck in the bathroom or take home.
The term draws parallels between real meat markets, where meat is hung up and displayed in plain view for people to look at, judge the quality of, and make decisions of whether to buy or not, and the atmosphere of many nightclubs/bars that are only seemingly in existance so individuals can display themselves to others for judgement and "aquisition", and likewise, size up and attempt to "aquire" others.
also used as an adjective to describe places possessing this quality.
