A DeNozzo is an obvious statement
made by an otherwise intelligent & intuitive
individual. Upon calling the subject a "DeNozzo" one will convey
heavy sarcasm.
"That's one big
bomb, Boss!"
said Agent DeNozzo.
"You think, DeNozzo?" said Agent Gibbs when confronted by a
bomb big enough to blow up the whole suburb & surrounding area.
