Bozo Blunder

Also known as “The Classic Bozo Blunder,”the Bozo Blunder is a impactful mistake made by the opponent or yourself, usually during a Chess game, that in hindsight was a move that gives the other person a large advantage. Please not that any given mistake is THE Bozo Blunder and not A Bozo Blunder, since each successive Bozo Blunder trumps older ones, seeing as you had the chance to improve but failed, defining the new standard for Bozo’s and Blunders everywhere.

P1: Nxd7 (?!)
P2: Is that really your move?
P1: yeah
P2: Well, that was the CLASSIC Bozo Blunder!
P2: Qxd7 (!!)

blunder biscuits

A reward despite mistakes or poor performance that makes someone or something appear undeserving

I can’t believe management is still giving Kyle the best leads after he fumbled that corporate sale last week. It’s total blunder biscuits.

Mizzy blunder

A blunder so extreme that all hope, pride and integrity has been lost for the individual that has committed the action. A Mizzy blunder may lead to friends and family losing respect for you and turn you into the laughing stock of any social group.

How are you gonna turn down that hot girl, that was such a Mizzy blunder!

Bobcat Boner Blunder

This one is simple, it is when a cat mistakes your boner for a mouse so it jumps and attacks it ferociously until it bleeds.

1. Hey Steve, my cat did a Bobcat Boner Blunder to me last night
