A "surprise" pulled out of a diaper by the kid ( or adult) who is wearing it and either smudged on the wall or handed to the responsible adult on scene.
I was babysitting Stan's son last night, and while I was watching football that dumbass kid threw his diaperwad right at my face. So I threw one back at him.
A derogatory name for someone of Middle-Eastern descent. Probably the most common usage is in reference to Selami bin Hiden, I mean Osama bin Laden. Especially given the circumstances in Iraq, a diaper head is not a good thing to be.
Those wearing a mask believing in and in total compliance with the government of the day will save them with a UBI Universal Basic Income cheque living their days out as an empty, low vibration being with little or no cognizance or understanding of the world around them, an 'empty' sleeve of sorts.
