Kramer Moment 

Someone who is "not a racist" suddenly going on a racist tirade in the presence of an individual or individuals who are of the ethnic background that the racist tirade is directed toward. Such an occurence was first discovered when Michael Richards (aka Kramer from Seinfeld) went on a racist tirade during a stand-up in which he verbally attacked a group of porch-monkeys that had been heckling him. Hence the name "Kramer Moment."

After Oswald soundly defeated his white friend, Irving, in a game of backgammon, Irving had a Kramer Moment in which he reffered to his black friend, Oswald, as "stupid nigger". Oswald immediately responded by pulling out a gat and busting a cap in Irving's scrawny white ass.

Kramers Moment 

In the 90's a series of Kramer's men's clothing ads were on TV depicting men in a still pose often with a gaze of reflection. The awkwardness of why they were posing like that, seemingly out of the blue became know as a Kramers Moment.

This supersedes the Kramer Moment in relation to the Seinfeld TV Series.

You can preemptively say Kramers moment to get a group of friends to pose like the commercial, or you could find someone already in a pose and ask them if they were having a Kramers moment.
