threadzilla 

An email thread involving 5 or more people who, when they all respond, the thread becomes longer, more difficult to accomplish the task at hand, and just generally monstrous. The more people respond, the worse it gets.

"This email thread has so many responses we aren't getting anything done."

"Time to get everyone on a conference call and quit screwing around with this threadzilla so we can get this resolved."
