1. When an episode of 24 turns out to have no action, just a bunch of filler. This usually occurs early in the season when useless subplots are being hashed out, as if anyone cares.
2. Based on the fact that when a certain contributor at a site called blogs4bauer participates in a liveblog of an episode of 24, the episode usually sucks...bad.
"Wow, tonight's episode was Wyattastic!"
"Dana Walsh is a moron and this episode is so Wyattastic"
"Looks like we have another Wyattastic episode, unless Jack Bauer pulls another knife out of his belly"
