1. A row of blue portable toilets.
2. Expensive escorts bought by rich Arab and European men to go on "yacht parties" for $30,000+ a piece. In reality these women are brought onto these boats to get shit and pissed on, hence the name Porta Potties.
Its easy to identify one of these women by the pictures they post on Facebook. If a friend of the female kind is always posting pictures of shopping sprees in Dubai and has a folder with nothing but pictures of her and friends on a yacht drinking champagne in any UAE or St. Tropez area she is a Porta Potty.
Fun Fact!: Some well known Porta Potties work at the Spearmint Rhino in Las Vegas.
Jane: "Did you see Tiffany's new watch/car/handbag/shoes? She just came back from a trip to Abu Dhabi and looks great!"
JoAnna: "I'm so jealous. How does she even afford those things? I've never seen her work a day in her life."
John: "She's one of those Porta Potties. Guys shit on her face."
