A man who, if provoked, will violently and savagely pound your girlfriend's orifices. They are well endowed and also very keen/smart about not getting caught. Usually they like to pull some mean shit on the girl they screw, because afterall, they do not love the whore they are out the door
Whoa, your girl looks like she ran into dejong last night.

Don't piss your girl off. She may backstab you and go find a dejong to take care of her needs
