mockumentary

a film that has the look and feel of a television documentary, but with the irreverent humor and slapstick of a comedy, designed to "mock" the documentary or subject it features.

"Drop Dead Gorgeous," which ridicules a local Minnesota beauty pageant, is the illegitimate child of "This Is Spinal Tap" -- a weak link in the people-are-stupid tradition. In that it portrays a group of film students making a documentary about a local witch legend, "The Blair Witch Project" is not unlike those "the making of" movie documentaries with which subscribers to HBO and Showtime are all too familiar.

A Momentary Lapse of Penis 

Thinking with your dick instead of your brain.

A slightly different take on Pink Floyd's 1987 album "A Momentary Lapse of Reason", used to describe the process in which the male anatomy overrides all rational decision making. Similarities can be drawn to "the heart wants what the heart wants", but "what the penis wants" is more powerful, visceral, and immediate.

Jack: Dude, you must have been beer goggling last night. That girl was such a butterface!
Jim: Yeah, I had a momentary lapse of penis.

John: Why the hell did I out my crush like that and admit to having all these feelings...I don't even like her that much!
Jake: Blame it on a momentary lapse of penis!

mockumentary

A show or film which parodies a "serious" documentary.

Movie examples include Spinal Tap, Drop Dead Gorgeous, The Specials (starring Rob Lowe, very underrated). One profound example on TV in Britain that nobody has mentioned is "Brass Eye" - a series of 6 documentaries and one special. They are available on DVD and video and are totally worth a look.
