Duffie

The practice of ruining your relationship with a boyfriend/girlfriend and then making your ex feel like shit through tactics such as: Sending them fake self-harming images titles "are you happy now?", fake crying where they can see you, kissing a random person in a night club and then telling your ex straight after.

Duffie-er:
"It's my fault the relationship broke down-- But here! Have all of my problems anyway"

Duffie-ee:
"...wow"
