Soccer mom
Suburban mother with 2.3 kids with hollow disciplines and automaton husbands with slowly diminishing spirits. Typically Caucasian. Their cabals are usually averted to music unfamiliar to that of their youth.
Soccer moms are mostly responsible for the gaggle of kid safe laws ranging from stop signs every two feet to inundating TV and video game ratings to the manufacture of the "V chip". They aspire to the halls of Congress and the floor of the Senate to champion causes in the name of their families at the cost of casual freedoms. 
They are reclusive, passive agressive, morally ambiguous and secretive. One should be wary of traveling through a soccer mom's natural habitat as your presence will be secretly alerted to by the authorities under vague and even false suspicions.  
They also reside in urban and metropolitan areas.
