A bro truck is one that is lifted by 3 inches or more, rolling on 33's with custom wheels, an exhaust outlet that can hold a watermelon, blacked out windows, glaring aftermarket lights, and usually the fastest vehicle on the road intimidating other drivers. They are all over here in Texas, it's basically a subculture really. I usually stay away from bro trucks while driving because they will cut you off and speed to no end and if they hit you their bumper is going straight through your windows. Fun fact, bro trucks spin out all the time when the roads are wet here and they have a high death rate due to rollovers.
I see that some of you have top trim level STOCK pickup trucks. Those are not bro trucks, what you have is a classy, luxurious pickup and I would consider you a normal member of society.
