Costanzaed It--the art of taking a seemingly sure thing and somehow fumbling it away, usually due to a temporary and false sense of empowerment or boldness.
Based on the Seinfeld character George who repeatedly snapped defeat from the jaws of victory.
Also: present tense "Costanza It", or to "Pull a Costanza"
1. Man, I sure Costanzaed It with that chick. We were sucking face and I asked her if she and her sister would go for a ride on the threeway freeway. She ditched me faster than a cat can lick its ass.
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?
The act of a guy leaving an article of clothing at the home of a girl that he slept with, so as to ensure that at a time in the future the girl will have to have him over to collect the item of clothing, thus increasing the chance of sexual intercourse.
I was with this girl last night, don't know how well it went but I Costanzaed her so hopefully I will get another go at it.
