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.
