I went to write "womit" into a Pros fic, and naturally I just wrote "Wallace and Gromit". But upon further reflection, I realized Wallace and Gromit is post-Bodie and Doyle, and therefore an anachronism. 
But for the life of me, I can't recall an earlier Cockney rhymish slang for this important word. Anyone have a better long long-term memory than mine?
This site is hilarious, by the way:

I should like to say I'm sorry for being so graceless as to mention this topic, but actually I'm pretty much unrepentant [heh].
This should be one I can answer, but the most common phrase I can remember (and it's not especially colorful) is simply 'throwing up'.
My memories of that time are hazy. I spent many of my younger days (nights) in a white echoey place 
The list on that site reminded me of a bit from Terry Pratchett's book (last continent?) where they are working out what Australian slang means.
We're a sorry bunch if we wax nostalgic over "barking at the ants" in our youth, eh?
Ralph? As in Ralph and Huey? Trouble is, although I distinctly remember hearing this being used at the time, it sounds totally un-British to me and was probably the result of people trying to sound clever. Unless it's actually true that it was invented by Billy Connolly.
Also heave or boke?
Not really germane, but Stalky & Co "catted".
So they did!!!! I'd forgotten - nice to be reminded! I was nuts about that book - but always felt strange about the sort-of-epilogue, somehow.
Ah, thanks to all for input on, erm, output.
I shall strive to put the advice to good use, heh.
