Selling out a Liberty Movement for some Trim.
That beta, Benedict Arnold sold us out.
It's when you get screwed over by the higher ups on your side, so you go to the enemy side in anger. It means that your superior "Pulled a Gates", which is screwing you over and/or stealing the credit. You've done a lot for the side, and you've got nothing to show for it except for insults, so you go to the enemy side in anger.
Example 1-God. my manager at Mc Donalds kept taking the credit for my great innovations and lowered my wage as an insult to injury, so I decided to work at Burger king. Yup, I just pulled a Benedict Arnold.
Example 2-I've been screwed over by the Soviet Union. They keep imprisoning me and stealing the credit. I'm going to be a defector. I'm going to pull a Benedict Arnold if this doesn't stop soon.
Joining the Other side after you got treated like crap by yours.
I'm being treated like crap by my Artistic"friends." Screw them, I'm going to pull a Benedict Arnold and join the Jocks.
Someone who betrays everything they stand for seemingly out of the blue. Generally used in a political context.
Originated from the real Benedict Arnold, an American general in the Revolutionary War who famously betrayed America.
Dude 1: did you hear about biden changing his opinion about gay marriage

A peice of shit school in Northampton where people smoke cigarettes because they can’t afford weed and where teenage girls pull each other’s hair
“Have you ever been to Malcolm Arnold academy”
“Yes it’s a shithole”
The real reason that he defected to the British side --- tubby prune-faced ol' "Key-and-lightning" Franklin had been overly friendly with him (and of course we know for sure that he didn't used petroleum jelly, either, since said lubricant wasn't even discovered until 1859!), and back then sexual-harassment lawsuits were virtually unheard of.
We all know that Mr. Franklin was a strong supporter of gay-friendly society, but after the Bennydicked Arnold affair, one has to seriously wonder if the enigmatic "Fart Proudly" essay-writer's orientation was itself at least partially "on the fence".
Got a girlfriend but little does he know his big ginger friend has been expanding her pussy everytime he hits it.
Oh no Wyatt don’t do the Matthew Arnold;)
