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:

Duffie is a very loyal girl. If she falls in love with you, she'll never cheat on you. She's usually a bit of a tomboy, but very pretty.
She also has a good sense of humor and can be very sarcastic. Duffie is nearly perfect.
''I made Duffie my girlfriend.''

''Wow, good job! You'll be happy together!''
