Mirth: noun. amusement, especially as expressed with laughter. An appropriate name for a vehicle in which to belt out, off-key the words to 'Bohemian Rhapsody'.
We've all had our own version of the "Mirth Mobile", likely your very first car. Mine was "Sir Lancelot the Hulk Intimidator". Sure, the name didn't flow as well as Garth's and I didn't have any cool flame decals; but I have a lot of memories of terrible dancing in it with equally terrible driving.
