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"

Duffy

In the act of sex, when the male is ready to ejaculate, he pulls out and inserts the tip of his penis into the nostril of the sex partner. And ejaculates inside of the nasal cavity. Ending result is sperm dripping down the throat of the sex partner.

Judy: Hey Amber why does your nose look all red?

Amber: Oh he Duffy'd me last night again.

Duffy

Fake; not sincere; lying

Look at that girl who acts like she is friends with everybody, she's hella Duffy.

That girl that flirts with everyone is a Duffy.

"hey man I got you a ticket to the superbowl" "no way you're Duffy."
