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.
