a no longer out-dated term for the telephone system. Now that AT&T has eaten up BellSouth, Ma Bell lives again. Watch her eat up the other surviving Baby Bells. She's like that evil robot in Terminator 2, whom they chopped up into bits and the bits melted and melded.

Aaaaauuuugggghhhh! Holy Jesus, no! It's Ma Bell! She's back! The dead live! THE DEAD FUCKING LIVE!!!!!
