This is the process of sending an e-mail then immediately going into sent mail and doing a SHIFT-DELETE to remove the e-mail without going throught the deleted items folder.  This is an appropriate tactic when sending sexually explicit e-mails that you don't want recorded by anyone.

Get the Shift-Deletemug. ctrl+shift+delete is a keyboard shortcut to delete history. Many find it quicker than going through settings; when your friend asks to borrow your computer, you just hit ctrl+shift+delete, click, and they'll never know what porn you were watching.
