when you act promiscuous, petty, spiteful, overbearing, rude, or if you know someone well enough it could be used as a term of endearment
after i see someone at the club grinding on my girlfriend i say out loud "What a DLS (dirty little slut)" and the girl has no idea what a DLS is, or when i talk to my best friend online and say "Hi DLS" it's used as a friendly term because we both know what it means and we are not using it literally...
