A fucktart discribes a worthless individual who, for some reason, you find yourself going back to time and time again. Someone who should be removed from the planet for the sake of all decent human beings. Someone who is a fucking idiot yet you enjoy sleeping with them.
aka fucktart
Completely annoying, detestable strain of human species. Mentally hindered to a point of retardation. Also used to express dismay at yourself, if you did something totally out of character, or just being outrightly stupid.
"Oh shit, I'm such a fuckwart, I left my keys in my car again!"
"That guy who tripped over his gran is such a fuckwart!"
Fucknaut is quite simply a term used to describe someone that is ‘way out there’ and ‘fucking oneself’. Basically, anyone that has done something obviously stupid, yet unpredictable.
