dufuss 

A dope, idiot, dummy. It's used not so much as a deep condemnation of character, as commentary of an incident or discrete act. And, meant to disparage the person at that moment for what occurred.

I appreciate that on yahoo it was noted that it's necessarily a mean thing to say

also dufus..........dufəs

I am such a dufuss. Every year I forget my Irish Aunt Trish's birthday, and have to ask my mother-in-law if it's exactly on St Patrick's day.

Happy birthday Trish

Hipster Dufus 

A word whose origins come from the hit television sitcom "Seinfeld". One of the recurring characters, Cosmo Kramer, had been called this (as far as I know, on more than one occasion).

I assume it's supposed to be an insult, referring to the person as someone who thinks they're cool, yet is (according to the insulter) quite the opposite.
