dilby 

A dilby is the person who we all know, they are notorious for being "that guy will do it" they seek attention and yearn to be wanted so bad that they will stop at nothing to gain it. They commonly will spend money on you while out, or if their broke, like most are, they will offer their services to you, "hey man want me to fix your car, take out your trash and clean your toilet?" And even sex if they are of the opposite side of the fence. They can be easily spotted in the crowd as the one who laughs at everything, and their laugh resembles the sound of brushing teeth.
