What is Mega Culpa?
1.
An apology for a big-time screw-up (from the Latin "mea culpa" for "my fault"). You would not issue a "mega culpa" for eating the last doughnut in the employee lounge, but for offenses such as, but not limited to, robbing a bank, knocking up your sister-in-law, being expelled from school for running an opium den in the boiler room, etc.
"Did you hear Michael Vick's mega culpa after he pleaded guilty to bankrolling that dogfighting operation?"
