n. Someone, typically a skater, surfer, or snowboarder dude whom you can count on. This person is laid back, mellow, chill, and doesn't trip. He is one of your homies. You articulate the word brobra as if you were Keanu Reeves in Point Break, or Jeff Spiccoli in Fast Times.
"Dude, careful with that board, it belongs to my brobra."
A girl who comes to close to crossing the line of dudeism by hanging around the dudes in their enviroment and participating in dude activities like surfing, skating, ect. These girls constantly use and abuse words like bro, ripping, shred, epic, rad, narly, dude, sick, bra, ect.
These chicks also dress like dudes,(baggy shorts, backward hats.)
That chick could be pretty hot if she was'nt so bro-bra.
