Equivalents in other languages

Origin: A copy of the older slang bourrer le crâne (to stuff the skull), which means exactly the same and pictures a head being packed with nonsense — the emptier the skull, the more easily it fills. Bourrer le mou seems to date from the First World War, and works because mou is slang for the brain among other things: soft, in other words, which it is. The variant gonfler le mou (to inflate it) circulated too, on the reasoning that anyone filling you with that much nonsense is doing a great deal of pumping. Céline drew c'est du mou from it in 1936, meaning that is a lie.
