Someone (usually a guy) who looks (physical features) and acts like the biggest dork ever. An extemely unattractive person who some how is married to a physically attractive person, or dates individuals that are way too good looking for him/her. These individuals (non-DFK's) somehow find a DFK attractive.
Did you see Amanda's husband at the get together? I can't believe she's married to a Dork Face Killa (DFK)!! She's too smokin for him!!!!!
