When something is so cold (usually weather) that your nipples are practically hard enough to dial the phone with. Also know as PHONE DIALIN' COLD.
"Yo you coming over tonight Susie?"
"Hell no you been outside lately? Its dialin' cold out there!" (Susie then hangs up on his ass)

"Hey Max whats good?" (shakes hands)
"Damn Ricky your hands are dialin' cold up in this bitch!"
(Ricky then proceeds to shove his hands down his pants to caress his warm testicles)
