"what does 'flow it, don't bro it' mean?"
"It means that when there is a "line" of lets say five features you don't stop with your friends in the middle of the line after each one. If you must stop, you go to the side of the groom and get out of the way. Many parks have areas that are made for stopping prior to hitting a line. These are called "Bro-Zones". Be good now!"
This guy's the best! :D
