Similar to Death by Flashback, except not immediate, not a flashback, and... actually not all that similar. Anyway, whenever the whole cast gets together to say "cheese", it's a good bet the vast majority of them will be horizontally-oriented in the very near future. Does not necessitate an actual photo—an obviously-meaningful wide shot will more than suffice—but when a photo is involved, things tend to be that much deathier.
