Nabagle
Having sex with someone else in your ex's group after you split up. It’s like you’re trying to make them feel like total failures.
I nabagled her in front of her ex’s whole group. They all laughed at her.
He nabagled my ex's best friend in the cafeteria. It was like a slap in the face.
I got nabagled by a guy who still had a crush on my ex. It was total embarrassment.
