Stall Sisters

Ones (usually always girls) who may, or may have sexual encounters in a public - bathroom stall or public bathroom, in a public place. They do this because: they probably don't have any where else to go; it could be the quickest place to go at that time. Or their just that much of a dirty slut (smut), that they just have to "get it in", & it doesn't obviously matter where they have sex; as long as they get it over with.
