situational awareness retard
anyone who walks or bikes around outside while being wholly immeresed in their ipod orwith their cellphone plastered to their ear, often looking straight ahead and being completely clueless about his/her surroundings. remember, darwin gets the smart rich ones too ya' know.
"hey, check out that chick walking straight across the intersection while gabbing on her cell phone. she didn't even bother to check for cars- what a situational awareness retard."
