Someone or something that is so cool and funny, that you could say they rock out loud. An unexspected event that pops up that makes you so happy you want to scream "That rocks out loud, man"
Katie unexpectedly got a phone call saying that Orlando Bloom was going to visit her, she screamed "Oh my gosh!!!, He rocks out loud."
