Fever Pitch Meaning

(idiomatic) Extreme excitement

Example: 2013, Delme Parfitt in Wales Online, Cardiff City 1 - 0 Swansea City: Steven Caulker heads Bluebirds to South Wales derby win (3 November 2013)
  After all the hype, all the fever pitch build-up, the encounter never really lived up to expectations - as is so often the case with derbies - and the atmosphere was even a little subdued at times.
