A close friend of Jerry Seinfeld in the show 'Seinfeld.' He keeps all of his receipts in his wallet at all times, which in turn he keeps in his back pocket. His wallet is so massive that, when sitting down at a resturaunt, he must put a stack of napkins beneath the other pocket to level himself. Played by Jason Alexander.
Hey, did you see the Seinfeld rerun last night?
Yeah, it was the one where George sleeps under his desk, and Jerry calls a bomb threat.
Oh George Costanza...that George Costanza, when will he ever learn?

Exactly who president Biden is supposed to play irl
Even if George Costanza was a fictional character on Seinfeld...well at least he did the opposite of what led him to screw up his life choices. Maybe Biden should do the opposite of everything he himself has done so far as president?

Based on the Seinfeld characted "George Costanza," 'George Costanzaing' is the act of taking back some of the money one has left for a tip, most often while the money is in the waitress/waiter's hand.
I totally George Costanzaed that waitress when I realized you left 15.00 on a 20 dollar tab!

I'm not one for George Costanzaing, but I refuse to leave more than 2 dollars for this waiter!

Referring to the Seinfeld episode where George's wallet was so overstuffed with junk that it made him sit at a tilt with it in his back pocket; forcing him to even it out by stuffing his other back pocket with napkins. Eventually, the wallet exceeds maximum density and explodes on the street in a shower of cash and receipts.
Hey! Don't over stuff that or it'll go like George Costanza's wallet!

A mental condition in which a person blames everyone else for his own failures.
Both Alex Ferguson and Jose Mourinho certainly have the George Costanza syndrome as they blame the referees for every one of their losses. Real Madrid fans have the George Constanza syndrome as they claim UEFA favors Barcelona FC over Real Madrid.

A George Costanza Answering Machine is when you record a ridiculous greeting people hear when they call your answering machine. It comes from an episode of "Seinfeld" where George's greeting is himself singing a song off key to avoid talking to his girlfriend.
I HATE calling Paul when he isn't home. He has a George Costanza Answering Machine.

An absolute failure of a dude who can’t even keep a steady job.
George: Every decision I have ever made in my life has been wrong. I guess thats because I’m George Costanza.
