Attempting to get permission to leave work early on any given day for a reason that is questionable in its legitimacy, or perhaps outright laughable. Often, the reason given will employ minor ailments such as getting "fuzz in one's eye" or "having a toothache". It is also preceded by a minimum of thirty minutes in which the individual must constantly groan, complain loudly to an unspecified and unsympathetic audience, close their eyes, grimace and ultimately create a spectacle which only further highlights the ludicrous nature of the stated discomfort.
Example 1: Did you hear that Vincent tried to leave work early today? He told Brian that his nose was too stuffed up and it was keeping him from hitting his quota. Brian knew he was just pulling a Kevin though and made him tough it out.
Example 2: Man, I was so hungover today that I decided on pulling a Kevin halfway through the day! Told them I felt sick and was going straight to the doctor, but really I just went home to get drunk again and watch Adventure Time in my boxers.
