To clooney-out means to age progressively well as a man. As women get older, their looks tend to fade. Men on the other hand season with age and become more attractive, like George Clooney.
"Bro, I haven't seen you in years. I'm dig'n the silver hair, the nice threads and the hot young girlfriend!"

"Ya gotta clooney-out bro... clooney-out."
