I hate "bruh" too...one of my son's used to say it all the time. He sounded like an idiot. He finally outgrew it.

Every time I hear it I picture some kid in skinny jeans that are so tight they're cutting off the circulation to his brain, hair hanging in his eyes because he's too lazy to pick his head all the way up, smoking weed with his pals in Mommy's basement and discussing how everybody's stupid but them, LOL
