When someone looks way too old for their age, possibly because of long term drug abuse or some other form of hard living. The term was first used on a Kanye West blog entry, where he described his older looking appearance on the cover of a magazine. The term has since been mostly used on dlisted.com to describe celebrities who look ridiculously old for their age.
Damn, Jenny and I are the same age but she looks at least 10 years older than me. That's some Benjamin Button's shit right there.
The imaginary phone you have with you when you forget your real phone.
Buxton's Phone is created each time reach for your phone despite the fact it's not with you. It vanishes the moment reality returns you to its terrible clutches. It is extremely lightweight, portable, undetectable by any modern technology, and waterproof, but unfortunately not compatible with any carrier or battery charger.
Bobby repeatedly reached for his Buxton's Phone every minute for two hours after leaving his real phone in his "sexy pants".
