Oversight
When you make a serious mistake but you don't want to admit that you fucked up, you say that "there was an oversight." Used in a professional setting as a futile attempt to make serious errors sound better.
Example:
"WHAT THE FUCK MAN WHY IS THERE BLOOD ALL OVER BOB?!! WHAT DID YOU DO?!!?"
"There was an oversight, alright? I didn't know the gun was loaded"
"YOU MOTHERFUCKER"
"WHAT THE FUCK MAN WHY IS THERE BLOOD ALL OVER BOB?!! WHAT DID YOU DO?!!?"
"There was an oversight, alright? I didn't know the gun was loaded"
"YOU MOTHERFUCKER"
