Tonehoffing is the art of stealthily replacing an unsuspecting friend's ring tone with an embarrassing song. Basically, it's Hasselhoffing but applied to a phone.
Dude, at the Save The World charity dinner last night, I took tonehoffing to a whole new level. Replaced Bill Gates's ring tone with that gay ass song from the Apple commercial. Steve Jobs crapped his pants it was so damn funny.
