Duffs

Deemed UnFit For Society
Used when describing someone that acts like they are a person who just escaped an insane asylum and doesn't belong among the common people

Person One: Dude did you see those new pics of lindsey lohan getting totally smashed at the party?

Person Two: No but I can imagine

Person One: Yeah it's not even funny anymore, she's been duffs in my book for a long time

Person Two: True that, she needs to do us all a favor and check herself into a clinic or asylum for that matter

Duff

Like a muff in every way but it is the masculine version.

I blew that guy, but his duff felt like a tumbleweed.
