chunder, v. — Green’s Dictionary of Slang

chunder v.

[according to Barry Humphries (b.1934), the great popularizer of the word in his ‘Barry Mackenzie’ strip in Private Eye and on film, f. naut. shout of warning ‘watch under!’; thus Humphries, Collected Barry Mackenzie (1988) ‘Jeez I’m sorry lady — I forget to yell watch under’. He also offers rhy. sl. f. Chunder Loo of Akim Foo = SE spew, to vomit. Chunder Loo featured in a long-running series of advertisements for Cobra boot polish (c.1910–29), drawn by Norman Lindsay (1879–1969) (and occas. by his brother Lionel) featured in the Sydney Bulletin. Thence it moved from public school sl. to surf jargon to popular use; Moore, Lexicon of Cadet Language (1993), adds ? link to UK dial. chounter/chunter/chunder, to grumble]
