A FUCKTART is someone who leaves you with literally a sour taste in your mouth after they leave your presence and who generally needs to have themselves FUCKED.
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.
