Occurs during a shouted conversation in a loud, crowded space. An embarrassing word or phrase is shouted when everyone else in the room suddenly goes quiet.
Originated in a classroom when a comment was made about a PlayStation game. This has now spread throughout the vernacular of school children in Aberdeen, Scotland.
Eoin (in a loud room): Do you remember the PS1?
Duncan: Yeah, it was great!
(Room suddenly becomes silent)
Eoin: Hercules was the best PS1 game ever!
Everyone else in room: What?! Hahahaha!
Duncan: Hercules moment! Waaaaaaay!
