A bro-dozer is a ultra lifted truck, usually with the front end jacked up as high as possible and made to look like some sort of white trash trophy truck. They are commonly 2wd and have the clearance of a snail in a lettuce field. They can be easily identified by having more speaker systems than Carter has liver pills.
They are normally driven by a "bro" which is someone who likes to start lots of fights and generally be a PITA to everyone within earshot around them. They commonly show up in places where peace and serenity is desired and provide everyone within earshot of them with the latest cool guy rap music. They can be easily spotted by their flat brimmed baseball style hats that they tuck the tops of their ears into. They commonly wear low knee length Dickie brand shorts with socks that come up over the calf. T-shirts may vary depending upon the species. I have heard they subsist on Monster Energy drinks or Red Bull. They are generally loathed by anyone who does any actual off roading and rock crawling. Membership into the "Bro" community generally consists of going to a Motorcross event and getting drunk to see how many fist fights you can get into. You get more points for getting arrested. If you get probation and have to wear an ankle bracelet GPS locator, you are automatically elevated to Hero-Bro status. Most of the time the "Bro" progresses into the modern day "tweeker" around the ripe old age of 24-25 that skulks about your local neighborhood during the wee hours of the morning in search of HID light bars and Toyo MT 35's that aren't locked to supplement their income.
This is, by far, the best and most accurate (and funniest) explaination of a bro and bro-dozer I've ever seen. Well done, sir! To add to the conversation - see also; bro-hoe or bro-ho: A member of the female gender who enjoys the male company of the above defined bro. In addition to being in the passenger seat of a bro-dozer, they can also be identified by their excessive trendy tattoos in highly visible places (it used to be that the tramp stamp was most popular, but the full sleeve or partial sleeve seems to be more popular of late), large fake breasts, overly-tanned skin, skimpy clothing, dyed-blonde hair and overly-applied lip liner.
