What is the slang contraction of "What'd he" as in the sentence "What'd he come at you with"? "What'd he" is already a contraction but I mean in the same manner like whatcha = what're you=what've you, for example. I made a comprehensive search, but I didn't find the answer. Is the slang contraction the same whether it's contraction of "What would he" or "What do he" or "What did he" etc? If there isn't the well-established contraction of "What'd he", how would you shorten it? What does the aforementioned sentence "What'd he come at you with" sound like when it's spoken very quickly as in a slang speech?
For how it actually sounds, spoken fast ...
What did he = What'd he = (?) W'a'd'ee
I think what'd he is the shortest form of "what did he..." that would be readily understood. You might get away with "what'dee" - as in "What'dee say?" Also:
"whatta ya" (what do you) "why'n'cha" (why don't you) "didja" (did you) and "why'd'ya" (why did you)
