A person from the burbs who have utter disregard for laws since they feel it don't apply to them
The snoburbian wanted his Starbucks and wifi but there was no where to park so he parked in the last handicapped space, creating a hardship for the person who needed it
The snobby suburbs of big cities where everyone drives a status car and the high school kids compete to see who has the most impressive college application, the most AP classes, etc. (originated in Melbourne, Australia)
He thinks he'll get into Yale because he lives in the snoburb of Potomac.
