"A deformed language in which the initial consonants of contiguous words are transposed" [OED], 1863, said to derive from the proper name of a Polish count. Compare spoonerism, which describes the same thing.
MARROWSKYING, subs. (general).—At the London University they had a way of disguising English (described by Albert Smith, in Mr. Ledbury, 1848, as the 'Gower-street dialect'), which consisted in transposing the initials of words; as 'poke a smipe' = smoke a pipe; 'flutter-by' = butterfly; 'stint of pout' = pint of stout; etc. This is often termed MARROWSKYING. [Farmer and Henley, "Slang and Its Analogues," 1896]
