One of the biggest time sinks in the MMORPG called World of Warcraft. People used to spend months getting reputation with the collected people, or Faction, of Silithus. May be used as a description of a time sink or something that takes way too long to finish (if ever finished).
If looking for annoyances that are synonymous, might I suggest looking up Barrens Chat?
Person 1: I swear, I was mowing lawns for my neighbors this last weekend, and this one lawn was a total Silithus.
Person 2: You poor, poor soul.
