Deep throat

[Little_Girl]

to perform fellatio (dick-sucking) to where the penis is sticking in the performers throat (usually causing a gag reflex);
title of a movie that referred to the act of deep throating;
name given to an informant figure who spoke to Woodward and Bernstein during the Washington Posts investigation of the Watergate break-in. His identity has essentially been kept a secret and has been the focus of a parlor guessing game in DC.
Some believe Deep Throat was either fake, a literary creation to sell the book All the Presidents Men, but too much surrounding evidence does suggest there was at least one deep source providing clues. The more likely scenario is that Deep Throat is indeed a merging of a handful of sources (despite Woodwards assertions its only one person) in order to both protect their identities as well as create a mesmerizing character in the book written about the investigation.
If Deep Throat is indeed one person, the most likely suspects are with the FBI, who were being pressured by the CIA (acting on Nixons orders, according to his own tape recordings) to cover up the whole mess, and who were fighting back as best they could against a White House that was threatening their relative independence within the government (during Hoovers lifetime, the FBI became a separate power unto itself, and with Hoovers death at the time of the break-in, that was being threatened).
