"Ass Dialing" is something usually achieved by people with very large, very talented asses who wear cell phones on belt clips. When they sit on their phones, random button presses result in random calls all over the world. The recipient of these calls hears nothing but a stream of DTMF button tones and muffled conversation.

accidentally making a phone from the cell phone in your pocket by sitting on it or otherwise having unintentionally applying pressure to the buttons
Take your phone out of your pocket. Quit ass dialing me. I'm sick of listening to you singing along to the radio.
