A ridiculously small, and usually overpriced conveyance driven by people who want to be sure they let you know they believe they are smarter than you. These people are liberals (libs...hence the term libmosine) and as such the names of the cars themselves must appeal their pretentious need to feel smarter than everyone else (obviously even though they arent). ie Smart Car.
Hahahahaha! Hey look at that moron in the libmosine! I bet he can fit a whole bag of organic produce in a reusable cloth bag acquired via free trade in the storage pocket in the rear of that thing!
