Feral
Poorly dressed, spoken and educated people at the lower end of the socio-economic scale. (See also Chav,Bogun,Trailer Trash) Known for their prowess at stealing cars and their utter disregard of birth control options. In addition to an extremely high swear-word vocabulary, their children have constantly running noses, dirty faces and unkempt hair.
Those kids are such ferals - I just heard the 5 year old say "F#$k you, man!"
