Elephant flatulence.
1950's London, 2 well dressed Congolese doctors having a corridor debate in a hospital. Its 'phoom', says one. Its 'phoowm' says the other. Nasal English doctor sidles up, I think you'll find it's 'womb'. Nah, mate, they say. You wouldn't know about elephant flatulence.

When something goes "phoom" it is expanding. Instead of saying "expand" you would say "phoom".
The opposite is "soom".
