See Pop the Collar.

A thing people do to imitate Count Chocula and his infamous Choclatey Popped Collar, otherwise commonly referred to as ChocoPop. But they fail to realize that they aren't the Count, and so they just look like fags.
I was eating cereal one day when I happened to notice the prevalent popped collar of Mr. Chocula.

adjective: working class. I don't know how it became OK to equate blue collar with redneck. I was born and raised just a few miles west of Manhattan (I'm from New Jersey); I don't wear a mullet or a wife beater; I don't drive a pickup truck; and I am an unabashed and unashamed liberal. I am not a redneck; I am blue collar, a member of the working class, and damned proud of it.
redneck: ah hate niggers, jews, catholics, librals, commies, rich people, and anyone else who's not like me.
blue collar: I work with my hands to create the goods and services that people in my community need. I may be of any race, gender, religious belief, sexual orientation, or political affiliation. Without people like me, this country would cease to exist as we know it.
