Big sad hour is a phrase used to show one's sorrow for someone else enduring a tough time. Usually it is not used for deaths or injury related events, but minor inconveniences in one's day-to-day life.
Hey man, how's it going?

Pretty bad bro, just got off a 10 hour shift at work.
Damn bro, that's a big sad hour
