The feeling you have the moment something happens that immediately sparks a sharp anger or rage inside but you DO NOT react to it. Instead you sit and dwell on it. The feeling waits for a second trigger for a response which may or may not happen.
"When my freind was hit with a beer I could see that the pilot light of anger in him was lit, and the night was going to get interesting."

"My pilot light of anger lit when she backed into my car."
