Mumistake 

To be caught up in the awkward situation of insulting somebody's mother, the mistake being that she's (supposedly) deceased.

Those seconds that follow the person's remark of their mother being dead are what define the word.

Act commonly consists of the person retracting their statement as a precautionary measure.

1: "My mum used to buy me Pop-Tarts
2: "Your mum is a Pop-Tart"
1: "My mum's dead."
2: "Oh. Mumistake. I didn't mean to... you sure she's dead?"
1: "No! Dick!"

1: "My mum used to buy me Pop-Tarts"
2: "Your mum is a Pop-Tart"
1: "My mum's dead."
2: "Oh. Mumistake. I didn't mean to... you sure she's dead?"
1: "Yes. I'm going home to cry myself to sleep."

America's greatest mistake 

The 45th President of the United States of America.

The 45th, in my humble opinion, will be America's greatest mistake.

French Mistake

When an otherwise straight male is persuaded to, or on a whim in the heat of the moment, engages in a homosexual act of which he later regrets and is ashamed.
Alluded to in the musical number of the same name in Mel Brooks' film "Blazing Saddles".

Having shared the intamacy of a small tent for so long, in the stress of jungle combat, Pierre and Gustav came close to making the French Mistake on many a steamy night.

Great Mistakes 

Nickname for the Navy's Recruit Training Command (boot camp) in Great Lakes, IL. So named for the regret felt by some recruits wondering just what they got themselves into.

I can't wait to see my wife when I finish up at Great Mistakes.

I've made a huge mistake 

A phrase used often in the canceled TV show "Arrested Development". The phrase is mostly used when the characters talk to themselves after a serious of poor choices/bad events. It's used to make light of bad situations, although the characters themselves don't find it funny.

MARTA: "I was really worried about you"
GOB: "You've got nothing to worry about. We're going to be together for a long time"
MARTA: "We're family now - I'm so happy. I'm going to call the kids!"
<MARTA walks out of room>
GOB: I've made a HUGE mistake
