A term used when referring to a cheap, trampy slut who obviously grew up without the guidance of a good mother at home when she was younger and then became an adult with no moral compass in life. A loose woman - usually of the trailer park brand. They typically smell like an ashtrsy and have really stupid tattoos of like a Disney character or a dumb saying and they've done their fair share of amateur porn with multiple partners.
"Dude, who the hell was that motherless slag that Steve brought to Tom's party last week who tried to f*ck every dude there? She looks like she just got sprung out of prison."
