I Knew You'd Trade in 300
You yell this at someone who betrays you, like they're a traitor who's not worth the trouble. It’s from the movie 300, where a guy flipped sides and got a face full of swords.
'I knew you'd trade in 300' when my friend took my lunch money and gave me a sandwich from the trash.
'I knew you'd trade in 300' after my dad took my side in the middle of a fight.
'I knew you'd trade in 300' when my cat knocked over my mom’s favorite vase.
