To have a face with no expression. Mouth opened with eyes, that say YOUR answer, your question, your comment, YOU ARE JUST DUMB!

***Named after Sean " Puffy-P.Diddy-Diddy" Combs
Which is taken from the expression that he gives his cast of Making of the Band, People with no Swag and Those who aren't on his level***

Therefore, I named his look the Diddy!
Cherise, this guy came up to me today, and tried to holla at me with his kids in the car. I looked at him, and gave him THE DIDDY, and kept it moving.

diddy is the alter ego of fair lawn resident matt devore. it started out as something that just surrfaced when he was intoxicated but soon carried over to be his nick name to all he is known too including complete strangers. along with the name comes a dance that just involes moving your hips and upper body in a side to side motion, it is simply called the "diddy". anyone who knows matt knows that this name fits him perfectly because like the real celebrity diddy he is just as smooth and black.
whats up diddy?
