Bladder buster 

An excessively lengthy event, such as a multi-hour class, meeting, show, line or worship service, that drags on without breaks and keeps its captive attendees from heeding nature's call, resulting in great discomfort, inability to pay attention, and, in the most severe cases, ruined clothes and seats.

That three-hour meeting was quite the bladder buster.
