Darwin Dangle
When a young woman, generally of less than 25 years of age and of low wealth, speed walks through a public setting (generally a train station, busy street, etc) wearing a velour track suit or other Juicy-inspired items while dangling her child (typically of an age that indicates she was knocked up in her mid-teens) behind her as if they are a both a fashion accessory and/or a massive inconvenience. In doing so, she will likely strut her stuff to attract any potential suitors. Heels are optional, but not required for a sighting.
Dude, I totally saw a Darwin Dangle in Ruggles Station last night.
