NOT so excellent when said sarcastically. Used in a derogatory manner to mean exactly the opposite of its true meaning. Said when a complete SNAFU occurs and usually inflected upwards at the end so that instead of saying the "EX" with more force, you gradually increase the pitch and distress in your voice as you follow through the word. Delivery of "excellent" is an art form mastered by the most sarcastic individuals who have experienced far too many fuck-ups. A cluster fuck expression.
