Facebook Wingman
A Facebook Wingman is the friend who makes your love life look bad just so he can feel good. He'll post your ex's face in a group chat or brag about how he's better than you. He’s not cool, but he’s usually drunk and doesn’t care.
I posted your ex’s face in the group chat and said you’re a total dweeb.
Your ex just sent me a message. I told her you broke up. #victory
I said you're still with your ex. I don’t know why.
