Hatesimping

When you have a falling out with your friend and they go to your mutual enemy to talk trash about you, all of a sudden they seem like insufferable besties when they hated each other just a few months ago.

"Whoa, why is Terry hanging out with Katy now? I thought they hated each other!"

"They did, but Terry had a disagreement with her ex bestie and now she's hatesimping."

"How did those two get so close so fast? Last I heard, Jeanie and Rose were sworn enemies!"

"Oh, they aren't really close, Jeanie is just hatesimping Rose right now because of some drama."

"The enemy of my enemy is my friend."
