Dudebro are usually of middle eastern or Balkanese decent. They flaunt what little money they have from working at their "cousin"'s gas station\party store, buying copious amounts of liquor when at drinking establishments and ending up belligerently drunk. Everything in their lives revolves around their one "cousin" that has all the tight shit they have at their disposal(usually lies, but in some isolated cases said cousin does exist). They are disrespectful towards all women.
When you enter their said place of business, usually a gas station\party store\coffee house\tobacconist\liquor emporium\car wash\quick lube\detailing shop... you, being a white or black person, are addressed as "Buddy", "Boss", "Cheif", "Dog" while being spoke to in broken English. When you are finished with your transaction they go back to their RAZR phone(isolated cases can afford Blackberry) and continue to talk to someone on the other line in their native tung. This is the only place in the world a Dudebro is kept in check.
