Doop

To describe someone who has no positive attributes, and is completely neutral in appearance. A "doop" usually is identified by their lack of money, a blank face, and unwillingness to achieve anything in life.

Man : Do you have that $5?
Doop : Well the thing is, I never actually have $5 on me at anytime...
Man : Your actually a massive Doop
