fucknucker
When you fail horrendously and can't think of some bland interjection, such as "shit!" or "fuck!"
"Dude, he just got dumped by the fifth person these past two months."
"Aw, fucknucker. That sucks, man."
"Aw, fucknucker. That sucks, man."
Fucknuck
Assholes that say they're gonna bring you a smoke n tell you to wait for them, and then they never show up or even text, wasting the time you could have used to find a smoke. Or anything else.
God, I wish Michel wasn't such a fucknuck.... I'd probably give him something nice.
