whuffo

n, a person who is not a skydiver (from the often-asked questions posed by prospective skydivers)
“whuffo you jump out of them airplanes?”
a person that has never made a skydive. a virgin to the experience of skydiving.

(interrogative, colloq.) african-american english for “why”, or more emphatically, “what for?”

‘ this was because their english teachers would wince and cover their ears and give them flunking grades and so on whenever they failed to speak like english aristocrats before the first world war. also: they were told that they were unworthy to speak or write their language if they couldn’t love or understand incomprehensible novels and plays about people long ago and far away, such as “ivanhoe”.

‘ the black people would not put up with this. they went on talking english every which way. they refused to read books they couldn’t understand — on the grounds they couldn’t understand them. they would ask such impudent questions as, “whuffo i want to read no “tale of two cities”? whuffo?
