Redenial

[Monty]

A portmanteau of redial and denial. this word refers to the act of pressing a random button on your phones keypad to erase the previously-called number from [the phones] memory, thus preventing anyone else from using the redial-button to find out what number you last called (extra points if you choose the # button for your sabotaging, since pressing this key merely produces a loud sarcastic-sounding repeat-beeping tone that makes the would-be [re-dialer] feel like hes being upbraidingly mocked for his nosy-inquisitive [temerity]).
