paraleipsis
pronunciation: pare-uh-layp-sis
definition: To say something by saying you're not going to mention it.
An example of paraleipsis might be, say, how a certain presidential candidate who called into question his opponent's ethics regarding the use of negative campaigning during the primaries produced his own negative ad then called a press conference to allow reporters from all the major networks to preview the ad (later aired on national news, of course) and hear how said certain presidential candidate would not be paying to run the ad because he just couldn't stoop to such mud-slinging.
Further, I won't point out the diabolical craftiness of his plan. I'm just here to report, you decide.
