The emotional state of Phialdelphia Eagles fans when something bad happens to the team. See McNabb injuries et al. The word is a combination of the acronym Tate(Talk about the Eagles) and the ancient hebrew word armageddon.
The Tate advisory level was raised to Tatergeddon after Donovan McNabb tore his ACL against the Tennessee Titans.
