(verb) The term for what happens when bros hurl half-formed insults at passersby, often while making obscene gestures.
"Dude, I got brossaulted earlier! They were all in a car- one of them hung his butt out the window and his friends screamed 'Fag' over and over!"

"What did you do?"

"Why, I smiled and waved, of course!"
